Hi all Every verb in English has three forms, namely base form, past simple and past participle. For convenience, we usually use V1 for base form, V2 - past simple and V3 - past participle when learning English in my country. But I've read some threads on this and it seems that native speakers aren't familiar with these terms. Maybe they're only common amongst learners. My question is: do you use V1, V2, V3 when learning/teaching English ? Are they common ? Thank you.
