Armed with the explanation I have moved onward and upward. However, when I wasn’t looking for it anymore(!), I stumbled upon a very succinct description of all the ‘that’ options last night.
It struck me that it mapped very well onto the variants run through in the challenges at the end of level 2 so I thought I would ‘share’ on the off chance it is of interest to anyone.
It is in the Gareth King’s Modern Welsh Dictionary but in the introduction covering grammar (not the reference section), the further brutal summary being:
Original idea begins with:
- Present tense: use bod
- Pretorite past tense: use ‘i’
- A verb representing any other tense e.g. byddwn or dylech etc: use ‘y’
- No verb at start - because sentence re-arranged for emphasis: use taw or mai
Simples!
I guess if you’ve got it already you’ve got it…but nevertheless its a very short explanation which is good for consolidation if nothing else!
