Example 2
# Vir elke Engelse woord moet   jy    een Afrikaanse woord   kies    en  dis   nie altyd  so duidelik wat   om te kies   nie.
: For each English word [must] [you] [one Afrikaans  word ] [choose] and it's  not always so clear    what  to    choose not.

  • <vaux><prn><det><adj><n><vblex> --> <prn><vaux><vblex><det><adj><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 may  sustain life]
  • <dem><n><vaux><vblex> -> <dem><vaux><vblex><n>
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>

  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>

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>

Detachable prefixes

* Ek tree op

     optree

Multi-prepositions

  • om met
  • om uit
  • oor te
  • om in
  • toe om
  • nou dat -> now that
  • uiteindelik -> at last
  • ... list more here ...

Verbs with attached prepositions

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

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>

Attributive = before noun Predicative = after noun

Adjectives in Afrikaans sometimes change depending on their position. Adjectives in the attributive position often morph. e.g.[2]

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).
