Do you ever forget a word completely?

Do you ever forget a word completely? It happens to me a lot—like, I’ll remember synonyms and even antonyms of a word, but the word itself just slips my mind. Sometimes I even have to Google something like “opposite of purple” just to finally remember the word I need. Thankfully, there are quick tools now to find antonyms, and they also give examples of how to use them in sentences.
