Question: What is the difference between "bresychen" and "bresych"
The dictionary says that "bresychen" is singular form. I wonder why
Welsh has a parallel system to singular/plural called the collective/singulative. For things that usually occur in groups, like many fruits and animals, you have one word to mean the thing as a collective, and then a word meaning a single specimen from that group. So bresych means cabbages in general or as a group, and bresychen is one single cabbage. Clêr is flies because they often swarm in a group, and cleren is one fly. Mefus is strawberries and mefusen is one strawberry.
