Correct spelling


Correct spelling, explanation: there is a rule saying that when a regular verb ends with y and we want to make a second or third form (past simple/past participle form) of this verb, we change y into i before adding suffix -ed. This way the verb try is tried in past simple. Tryed is, at the same time, an incorrect form. The correct spelling is tried.

Definition of tried:
verb, past simple and past participle form of try, to make an attempt to do something; about food: to taste
I’ve tried to ask her out so many times but I’m too shy!
Did you try the salad? It’s delicious.

Incorrect spelling


Incorrect spelling, explanation: tryed is incorrect, because, according to the rule, y transforms to i with regular second and third form verbs (if the verb ends with y). Therefore past simple and past participle form of try is tried (try: yi + -ed).
