Compound prepositions

<donnek> I've also thought of another wrinkle - compound prepositions
<spectie> i will probably need to write a rule
<donnek> eg ar ben (on top of)
<donnek> lit on head
<spectie> we can do a similar thing with those
<spectie> for example:
<donnek> becomes ar fy mhen (on my head, literally) = on top of me
<donnek> ar ei ben, ar ei phen, ar ein pennau
<spectie> are there many of them
<donnek> maybe we don't need to think about them now, but just to flag them for later
<spectie> if there are not many it might be worth making them multiwords
<donnek> how do multiwords work
<spectie> there are a few ways
<spectie> depending on if one of the words inside the multiword inflects or not
<donnek> that would be the case here
<spectie> for example "take care"
<spectie> "i take care of", "you take care of", "he takes care of"
<spectie> but "take care" is treated as one verb
<donnek> ok

Attributive and predicative adjectives

<spectie> its a problem with attributive/predicative
<donnek> it's say something (which is) nice
<spectie> but in english we don't distinguish between the two (at least in terms of morphology)
<spectie> yes
<spectie> in afrikaans they have a -e for attributive (e.g. feodale stelsel -- feudal system) 
<spectie> and "the system is feudal" - "die stelsel is feodaal"
<spectie> donnek, aye
<donnek> in Welsh the second would have yn before the adj
<donnek> so we may not need anything to mark attrib/pred

• Dywedodd rhywbeth neis wrthi = He said something nice to her
• Mae'r peth yno yn neis = That thing is nice

Mae yr peth yno yn neis

• Mae'n gar neis = It is a nice car

Mae yn gar neis

<donnek> at first glance, we may just need a rule for rhyw+thing
<donnek> rhyw = some
<donnek> rhywbeth (something), rhywfaint (somewhat), etc
<donnek> rhywle (somewhere)

Possession

 Mae            cath 'da    Bwflw
 Bod+p1.sg.pres cath  gyda  Bwflw
 Be+p1.sg.pres  cat   with  Beefalo
`Beefalo has a cat'

Apertium notes

We can probably deal with this in interchunk as follows

vbbod NP1 pr_gyda NP2

->

NP2 vbhave NP1

The 'yn' particle

As well as meaning 'in', 'yn' is used to form the present participle of a verb in welsh. For example:

• dysgu = to learn
• yn dysgu = learning

The present tense is formed by combining 'yn' with the corresponding form of 'bod' (to be) as follows:

• Mae Beefalo yn gweithio = Beefalo is working/Beefalo works

Note: when following a vowel, yn is abbreviated to 'n, e.g.

• Mae Beefalo'n gweithio

Genitive Phrases

To form the indefinite genitive, a simple construct of <object><subject> can be used. For example, "Soldiers of Wales" would be "milwyr Cymru", literally "soldier Wales"

Definite genitives are formed with a similar construction, just with the addition of y between the object and the subject. For example, "Beic y gath" = "The cat's bike" literally "bike the cat" Note: feminine nouns incur a soft mutation after the word "y"
