Seriously.
While working during a kind of busy period at the public library when we couldn’t get much done, a co-worker and I amused ourselves by making grammar jokes. By way of background, Co-worker was looking at the Wikipedia article on declension (she’s trying to learn Croatian, of all languages), and we found a ton of cases we had never heard of. So we started making up definitions for them. Here’s some of the best ones:
Ergative: case in which the noun is most comfortable
Absolutive: used by dictators, tyrants, and autocrats
Pergative: used by mythical horses
Temporal: only works for the time being
Elative: used when you’re really happy
Excessive: …actually, this is funny on its own
I have to stop looking at that page, because I could go on forever making declension jokes. Sick, isn’t it? 🙂
