The verb is merely, obey.

I obey, you obey, he, she, it obeys.

One may be obedient to someone, but one does not "obey to" someone.

Obey is already a verb.

For example "to obey someone or something" is an action, therefore it is a verb.

Obey is present tense.

I/We/You/They obey

He/She/It obeys

There is dis obey the prefix here is dis because it comes right before obey.

You can use Re obey because you can obey someone another time for the same thing maybe.

But everybody knows that you can use dis obey and maybe re obey

Onother person: Prefixes can be dis-obey
