One of the most challenging things in teaching a foreign language is to widen a student's vocabulary, especially to get them to use a bigger variety of adjectives. Once they have learned 'good', 'nice' and 'interesting' they seem to be absolutely satisfied with the choice of adjectives they have. Sometimes I 'ban' these words for one or two lessons to make my students leave the comfort and ease of the 'nice-good-interesting' territory. An advanced student of mine (no doubt remembering this struggle for synonyms) has recently showed me a video and asked me if this was what I had meant by using as many synonyms as possible. What could I have said? Well, it seems overdoing it a bit, but yes, the message gets delivered here. You could even say that it gets hammered in, I suppose. Especially if you use each of them ten times.
