This is a bit of an esoteric question, so I am probably calling @garethrking here.
I have been reading a YA novel yn y Gymraeg that has introduced me to a second type of short form past tense where (for example) the third person singular form ends in ai rather than odd.
I have done a bit of digging and as I understand it, this is used for:
Incomplete events in the past (where in English we would say ‘was doing something’.
E.g. Sefai yn y drws pan clywodd hi hynna. (She was standing in the doorway when she heard that.)
Habitual events in the past (where in English we would say, ‘used to do something’)
e.g. Gwisgai hi ddillad goch yn y gaeaf. (She used to where red clothes in the winter)
The future perfect (ie the past tense of ‘will do’, which in English is ‘would do’
Temlai hi’n wahangol yn y bore. (She would feel different in the morning.)
So - my questions:
- Errors of spelling, mutation etc apart, have I got this broadly right?
- Are the first two straight short-form equivalents of ‘oedd hi / oedd hi’n arfer + verbnoun’ or is there a more subtle distinction here?
- For the third one, could you also say ‘byddai hi’n teimlo yn wahangol yn y bore’ or does that not work for the future perfect in Welsh?
Thank you from a self-confessed grammar nerd.
