Do we use "less" only with comparative adjectives that take "more"? Can we use "less" with all two- syllable adjectives? less ugly- less happy- less narrow

Do we use "less" only with comparative adjectives that take "more"?

No. I was less rich than I had hoped to be.

Can we use "less" with all two- syllable adjectives? less ugly- less happy- less narrow

No. It's not appropriate to use 'less' with most ungradable adjectives.
