Regular verbs are easy to conjugate, just add “ed”:
play→ I played all night
team → they teamed up to defeat the boss
The problem comes with irregular verbs:
do → I did my homework last night
pay → I paid $20 for ‘early bird’ registration
buy → I bought the FGC yearbook
sell → I sold my stick
take → I took the train
catch → I caught the train (I nearly missed it)
post → I posted a photo of my food at the restaurant
study → I studied the tech
won → she won the match
Generally, irregular verbs ending in
- -y → ied e.g. try → tried
subject + didn’t + [infinitive without to]
o: I didn’t play anything yesterday
x: I didn’t played
I didn’t go to the event
Did + subject + [infinitive without to]
