Irregular verbs. Part 2

[man of manners]

Hi!
Please, could anyone provide examples of verbs that are conjugated differently when there is some new part added to the original verb, the same way as a prefix, to form a new word?
Ex: Cost "To require a sum of money to enable you to afford it." ..........> cost - cost
Accost "To approach someone and speak to them, especially aggressively." ...........> accosted - accosted

Thanks in advance!

Accost is not formed by adding a prefix to the word we now now as cost, which comes from a different root.

I do know this. I have said "the same way as a prefix". I meant adding an additional part to the word. I did not say "as a prefix".

Nothing was added to the word we now know as cost to make accost.

OK, they are two different words from two different roots but one of them "cost" is part of the other "accost" in just the form.

pit -> pitted; spit -> spat
say -> said; essay -> essayed
see -> saw; fricassee -> fricasseed

Is that what you mean?

Oh, yes yes. This is exactly what I mean. If you can provide more, I will be grateful.

I could provided hundreds more, but it would be an effort. Why don't you post a list of about 20 first. It would be best to start with short irregular verbs (which in most cases become regular when other letters are 'added'). This is more of a game than anything linguistically interesting.

have -> had; shave-> shaved; behave-> behaved.
be -> was/were; cube-> cubed.

PS: Others can help too.

I meant other learners mostly. It would be a good exercise - not so much for native speakers. As I said, it's more of a game than anything.

I will collect them now then post them.
