We are often caught on the back foot when we're asked about antonyms for some words like disgruntled. Most of us haven't really seen the word gruntled being used often and that's because there's no word as such.

We've compiled a list of these seemingly common words that have antonyms, unknown to most of us.

How many did you get right? Do let us know in the comment section.
