If you don’t know how to use the words, don’t use them. People are not impressed when you use words with 3 syllables simply to use big words. This is doubly true when you use it *wrong.* Don’t use query when you mean question. It just calls out that you want to sound smart. And learn the difference between similar words – constrained <> constricted, for instance. And awkward sentence construction doesn’t sound educated – it sounds like you don’t know how to construct a sentence.
