What is the antonym for the verb "support"?

For example: I support Bob's decision to quit his job.

What word could you use in place of support to make that sentence have the opposite meaning?


Solution 1:

Depends very much on what you mean by opposite. If you mean that I am against Bob's decision to quit his job, then GEdgar's suggestions, along with a myriad of synonyms and antonyms from thesaurus, will do

I oppose Bob's decision...

I reject Bob's decision...

However, if you mean that you are not in favor of, but not necessarily against Bob's decision, then it could be

I don't support Bob's decision...
