Is contreversial a synonym

Answer 1

The word, controversial, is spelled with two o's and one e, and yes, it is a synonym. Controversial also has synonyms, i.e., words of like meaning.

You can look at a group of synonyms like a flock of birds. Each bird in the flock has all the others as fellows. So each word in a synonymous group has all the others as synonyms.

The word controversial is a synonym for all these words and many more, according to context: arguable, debatable, contentious, disputable, doubtful, dubious, moot

And all those words are synonyms for controversial, too.
