I thought thesauri were designed to point out synonyms. But also show which adjectives can be interchangeable.

I thought it'd be a good tool for a writer wishing express themselves with more variety.

Have you tried working with analogies? There are workbooks available which range from pre-school age through adult, and can help you become more flexible in all sorts of vocabulary and its associations. It can also become a fun exercise to challenge yourself on fluency and the varied ways in which something can be described.

I realized something else that might help me though. See, I remember in school, I looked up words the old fashioned way. By dictionary. I didn't have easy access to internet. And even on the occasion I did, we were usually supposed to write definitions down by hand.

So maybe that'd help to remember them better instead of flipping from one word to another. Writing things down help to make it stick. Plus, I be spending a wee bit more time with definition individually. I have done this in ages, but it seems worth a shot.

Particularly, How does one expand it? I think in order to write, my vocabulary needs to be better. More expansive.
