This file contains some observations and a general "TODO" list / discussion.
# Afrikaans : lit. English @ English * Solutions?
Tagger
A tagger needs to be generated. Currently both en-af.prob and af-en.prob are copies of the de-en.prob
Transfer
Both directions
Synthetic to analytic adjectives
Adjectives that are like 'foo', 'fooer', 'fooest' should be translated as 'foo', 'more foo', 'the most foo' sometimes in both directions.
Automatically deriving adjectives from past participles
In both English and Afrikaans, many past participles can act as adjectives. If this property is exploited, both the Afrikaans and English dictionaries should shrink.
Afrikaans to English
SOV to SVO transfer
Example 1
# nie een van hulle die taal kan praat nie. : not one of them the language can speak not. NP NP V @ [not one of them] [can speak not] [the language] NP V NP
Example 4
# Ek dink hulle sal hulp waardeer van mense wat Afrikaans ken : I think they will help appreciate of people who Afrikaans know <prpers> <vblex> <prpers> <vaux> <n> <vblex> <pr> <n> <rel> <n> <vblex> NP VBLEX NP VAUX NP VBLEX PR NP REL NP VBLEX I think they [will help appreciate] of people [who Afrikaans know] I think they [will appreciate help] of people who Afrikaans know I think they will appreciate help of people [who know Afrikaans] @ I think they will appreciate help of people who know Afrikaans.
- <rel> <n> <vblex> -> <rel> <vblex> <n>
- <vaux> <n> <vblex> -> <vaux> <vblex> <n>
Example 3
# Sterrekundiges kondig die ontdekking aan van Gliese 581 c, 'n Aarde-agtige planeet buite ons sonnestelsel wat lewe mag onderhou : Astronomers announce the discovery of Gliese 581 c, an Earth-like planet outside our solar system that life may sustain Astronomers announce the discovery of Gliese 581 c, an Earth-like planet outside our solar system [that life may sustain] @ Astronomers announce the discovery of Gliese 581 c, an Earth-like planet outside our solar system [that may sustain life]
- <dem><n><vaux><vblex> -> <dem><vaux><vblex><n>
Example 5
# Sy het later badkamer toe gevlug nadat sy hulle sonder sukses gevra het om te bedaar. : She had [later bathroom toward fled after] [she them without success asked had ] to calm down. ADV N PR VBLEX PR PRN PRN PR N V V ADV VBLEX PR N PR PRN V PR N V PRN : She had [later fled toward bathroom after] [she had without success asked them] to calm down. @ She had later fled toward bathroom after she had without success asked them to calm down. or @ She had later fled toward bathroom after she had asked him to calm down without success.
Double negatives
# nie een van hulle die taal kan praat nie. : not one of them the language can speak not. @ [not one of them] [can speak] [the language]
One solution:
- <vaux><vblex>nie --> <vaux><vblex>
Or... basically drop the extra negative at the end of all sentences (well, at the full stop).
- nie<sent> --> <sent>
Example 1
# Ek is nie so bekend met presies hoe die opstelling werk nie : I am not so familiar with exactly how the setup works not @ I am not so familiar with exactly how the setup works
Constructions with 'do'
# Nee, ek het ook nie 'n idee wat dit beteken nie No, I [have also not] an idea what it means not No, I [also have not] an idea what it means No, I [also do not have] an idea what it means No, I [also don't have] an idea what it means @ No, I don't have an idea what it means either
Tenses
The ge<verb> construction
- Fixed — If broken, report a bug!
The past tense is formed regularly by adding the prefix ge- to the verb's infinitive/present form.
- Ek breek - I break
- Ek het gebreek - I broke, I have broken, I had broken
het gebreek ^het<vaux><pres>$ ^ge<past><prefix>+breek<vblex><inf>$ = breek<vblex><past> = break<vblex><past>
Separable verbs
- Main article: Separable verbs
- Ek tree op as verteenwoordiger"
- I act as representative"
tree op op+tree optree
= act or perform
- Sterrekundiges kondig [die ontdekking] aan.
- Astronomers announce [the discovery].
konding <NP> aan aan+kondig aankondig
= announce.
- Other examples
e.g. terugkry, oopmaak, weghardloop, teruggebring, aankondig, afkondig, verkondig, opgedaag, aangerand, aangesê, teëgekom, weggekom, uitgeklim
For example:
teruggekry terug+ge+kry back+PAST+get = got back
List of prepositions: terug, oop, op, weg, aan, af, ver, teë, uit, ...
More examples: that don't work!!!
aangery aan+ge+ry lit. on+PAST+ride = rode on = drove
grootgeword groot+ge+word lit. big+PAST+become = became big = grew up
Multi-prepositions
- om met
- om uit
- oor te
- om in
- toe om
- nou dat -> now that
- uiteindelik -> at last
- ... list more here ...
Generating correct tense forms
- Ek gaan ... verbind -> I will connect
- Ek het gaan verbind -> I have gone to connect
The problem is that we have to wait until interchunk to find out if the verb is next to 'gaan' or not.
English to Afrikaans
Adjective inflection
- Fixed — If broken, report a bug!
Attributive = before noun Predicative = after noun
Adjectives in Afrikaans sometimes change depending on their position. Adjectives in the attributive position often morph. e.g.[1]
Die blompot is goud. > Die goue blompot. The vase is gold. > The golden vase. goud -> goue This man is most famous , this is the most famous man Hierdie man is die meeste beroemd, hierdie is die mees beroemde man
Rule that says:
- <adj><noun> -> <adj><attr><noun>
- <noun><adj> -> <noun><adj><pred>
Determiners
His dog is red. Sy hond is rooi. This is his dog, the dog is his = Dit is sy hond, die hond is syne.
Verbs
That was a nice = Dit was lekker, Dit was lekker gewees It was a good poem = Dit was 'n goeie gedig, dit was 'n goeie gedig gewees It will be a good poem = dit sal 'n goeie gedig wees It would have been a good poem = Dit sou 'n goeie gedig gewees het. it would have been a good idea = dit sou 'n goeie idee wees, dit sou 'n goeie idee gewees het (both correct) it would have been a good poem = dit sou 'n goeie gedig gewees het (only this form is correct)
Separable verbs
afskei, oplaai, inkoop, aftel
Ek het dit op die kar gelaai. I have it into the car loaded. I loaded it onto the car
Present progressive
to be + verb gerund -> verb present + tans
Note, this is not perfect because many times English uses the present progressive (e.g. I am writing a letter) where Afrikaans would use the present indicative (e.g. I write a letter).
- Examples
"The highest point is currently being debated" Die hoogste punt word huidiglik gedebatteer `The highest point become currently debated'
"The boy is being selfish" Die seun is besig om selfsugtig te wees `The boy is busy ** selfish to be'
"I am eating" Ek eet `I eat'
Passive sentence structure
- Passive
- [In other countries] [trade unions] are actively suppressed [by political or military regimes]
- [In ander lande] word [vakbonde] aktief onderdruk [deur politieke en militêre regimes]
* [trade unions] are actively suppressed [by regimes] * NP VBSER ADV VBLEX+PAST PR NP * word [vakbonde] aktief onderdruk [deur regimes] * BECOME NP ADV VBLEX PR NP * NP VBSER ADV VBLEX+PAST PR NP -> VBLEX NP ADV VBLEX PR NP
Perhaps we need to have a separate tag for "to become" ?
"word" ("ge-") vb. (copula) become, get (angry, cold, dark, drunk, late, tired); grow (old); go (blind, mad); turn (grey, pale, Democrat); fall (due, dumb, silent, ill, in love); (pass. auxiliary) is, are, (infml.) get;
- Active
- [In other countries political or military regimes] actively suppress [trade unions]
- [In ander lande] onderdruk [politieke en militêre regimes] [vakbonde] aktief
Double helpwerkwoorde
<Anrie> "was die kodenaam het gegee" = "was die kodenaam gegee" (no "het") <Anrie> I think in this instance there is no "het", because we already have "was" <Anrie> Thus: I saw him - Ek het hom gesien, but He was seen - Hy was gesien
Infinitives
another preposition: "to" do something = "om" iets "te" doen, thus it's not "sy missie: na behaal", but "sy missie: om te behaal" (of course, this isn't strictly correct, since the verb should come at the end, but I assume we're leaving those type of errors for now)

Literary Afrikaans
Listed below are the first two pages of Ons is nie almal so nie by Jeanne Goosen. I decided a few days ago that it might be beneficial to focus on more than just academic Afrikaans, which is why I have listed the translations below of the first two pages from the original Afrikaans text to the English translation made by Apertium. If you decide to pursue the advancement/development of literary Afrikaans along with academic Afrikaans, I can post more excerpts (tspier2).
My ma en ant Mavis hou langs die hoenderhok stil met my pa se Plymouth. Hulle raas en lag so dat ou mrs Haasbroek se hond oorkant die straat begin blaf. "Sjoes!" skree ant Mavis. Hulle kom by die agterdeur in. "Was my kind soet?" vra my ma. Sy haal 'n pakkie uit haar sak, hou dit teen die lig en lees: "Which twin has the Tony ..." Ant Mavis sit die water op vir tee. "Ag, ou Doris," sê sy, "jy gaan mos 'n goeie job maak van my perm, nè?" "Don't fear when Doris is near," lag my ma. "Gertie," sê sy vir my, "gaan haal vir ons bordjies." Sy haal drie doughnuts uit 'n kardoes. Ant Mavis kry die koppies reg en my ma sit 'n doughnut op elke bordjie. Ons gaan sit by die kombuistafel. "Nothing to beat die Homepride se doughnuts," sê ant Mavis met 'n vol mond. "Eet my kind lekker?" vra my ma. Sy buk vooroor en soen my.
- My mother and ant Mavis keep next to the hoenderhok stil with my father's Plymouth. They raas and lag so that old mrs Haasbroek 's dog oorkant the street underway blaf. "Sjoes!" skree ant Mavis. They come at the agterdeur in. "Were my soet child?" ask my mother. She fetch a packet from her sack, keep it at the light and read: "Which twin has the Tony ..." Ant Mavis put the water on for tee. "Deem, old Doris," say her, "you go moss a good job make of my perm, nè?" "Don't fear when Doris are near," lag my mother. "Gertie," say she for my, "go fetch for us bordjies." She fetch three doughnuts from a kardoes. Ant Mavis get the cups right and my mother put a doughnut on each bordjie. We go put at the kombuistafel. "Nothing to beat the Homepride 's doughnuts," say ant Mavis with a full mouth. "Eat my child lekker?" ask my mother. His buk vooroor and soen my.
Ant Mavis kap saggies op my kop met haar teelepel. "Ou, blou-oog!" Ek lag. My ma en ant Mavis kan partykeer so snaaks wees. "Gertie," sê my ma, "gaan haal gou vir ons die lang spieel in Ma-hulle se kamer, dan gaan sit jy soet op die vloer met jou puzzle. Ons gaan ant Mavis se hare perm." Sy vat-vat aan haar eie hare, maak haar oë groot. "Ou Tank gaan sy girl nie ken as hy haar vanaand sien nie. Skoon seesiek gaan hy word van al die waves." Ant Mavis en my ma werk in die aande en een Saterdagmiddag in die maand met die matinées in Parow se Victoria bioscope. Hulle is usherettes. Ant Mavis is my ma se beste vriendin. Sy en my ma dra swart skirts en wit blouse as hulle gan usher. Hulle dra ook 'n ronde, plat hoedjie agter op hul koppe wat met hairpins vasgesteek word. Eintlik is dit nie 'n hoed nie. Dit lyk meer soos die ronde pannetjies waarin my ma koek bak vir wanneer my oupa kom kuier. Net dieper. Ant Mavis is vet en jolly. Sy blaas rook deur haar neus wanneer sy 'n Cavalla aansteek.Sy kuier omtrent elke môre by ons. Partykeer sit sy en my ma op die voorhuisvloer en speel plate op ons Pilot. Hulle hou van musicals soos "Showboat" en "Naughty Marietta." My ma het al Jeanette MacDonald en Nelson Eddy se plate. Elke keer wanneer my ma "Maytime" speel, sing sy en ant Mavis saam wanneer Jeanette MacDonald by die stuk kom waar sy "Sweetheart, sweetheart" sing. Hulle oë word dan vol trane.
- Ant Mavis kap saggies on my kop with her teelepel. "Old, blue-eye!" I lag. My mother and ant Mavis can partykeer so snaaks be. "Gertie," say my mother, "go fetch quickly for us the long spieel in adj>-they 's room, then go put you soet on the vloer with your puzzle. We go ant Mavis 's hair perm." She seizes-seize to her own hair, make her large eyes. "Old Tank go his girl not know as he adj> vanaand see . Clean seesiek go he becomes of already the waves." Ant Mavis and my adj> work in the evenings and one Saturday midday in the month with the matinées in Parow 's Victoria bioscope. They are usherettes. Ant Mavis are my mother's best vriendin. She and my mother carry black skirts and white blouse as them gan usher. They carry also a ronde, plat hoedjie after on their koppe what with hairpins vasgesteek become. To tell the truth are it not a hoed . It looks more like the ronde pannetjies wherein my adj> koek bak for when my oupa come visit. Only deeper. Ant Mavis are adj> and jolly. His blaas smoke by her neus when she a Cavalla aansteek.She visits almost each môre at us. Partykeer put her and my mother on the voorhuisvloer and play records on us Pilot. They keep of musicals like "Showboat" and "Naughty Marietta." My mother have already Jeanette MacDonald and Nelson Eddy 's records. Each time when my adj> "Maytime" play, sing her and ant Mavis together when Jeanette MacDonald at the stuk come where she "Sweetheart, sweetheart" sing. Them become eyes then full tears.
