A British English teacher told me here that the word effect is a noun. However, while I was looking for the meaning of perpetrate, I found its synonym effect.

My question is, can this affect its word class; lexical/open class? In other words, shouldn’t its synonym be affect as long as the word perpetrate is a verb?

Thank you.

A British English teacher told me here that the word effect is a noun.

No.

ems was talking about the word 'effect' in a different context.

 

[probus]

Effect is used both as a verb and as a noun.

In addition, I did not say in that thread that "effect" is a noun. I said that the word used should have been "affect". I referred only to the sentence you posted in that other thread and I did not mention nouns or verbs.

As probus said, "effect" can be a verb or a noun.
