I'm getting confuse with the words above, for me It seems that inadequate points out something not good enough, while unsuitable and inappropriate are synonyms, but I'm not sure, I think the examples to clarify my doubt are not necessary, so what do you think about?

I'm grateful!

Inappropriate and unsuitable are both qualitative adjectives.They describe the quality of something, and are very similar in meaning and usage. They are both placed as modifiers before nouns and they are both used as complements after the verb be, although inappropriate is perhaps more commonly used in this way, especially with the pronoun it.

inappropriate to/for something: Her clothes were inappropriate to/for the occasion

inappropriate (for somebody/something) (to do something) : It would be inappropriate for me to comment.

unsuitable (for somebody/something): He was wearing shoes that were totally unsuitable for climbing.


The clothes she was wearing were quite unsuitable/inappropriate for the cold weather.

They considered him quite unsuitable for their daughter.

Does this dress suit me? No, it doesn’t. And it's very unsuitable/inappropriate for formal occasions.

If something is inadequate, there isn’t enough of it or it is not good enough. Usage of this adjective often denotes quantity instead of quality, whereas inappropriate and unsuitable suggest a qualitative response to something.

inadequate for something :The system is inadequate for the tasks it has to perform.

inadequate to do something :The food supplies are inadequate to meet the needs of the hungry.
