In high school a friend and I “adopted a word.” There was a website where you would receive a random (and not commonly used) word to integrate into your lexicon so that the word would not go out of use. (words that wane in popularity are dropped from the dictionary)

I forget what the word was. 😅

But I do keep a running lists of new words I read and love:

indefatigable: persisting tirelessly.

parsimonious: unwilling to spend money or use resources.

phallogocentrism: the privileging of the masculine in the construction of meaning.

tautology: the saying of the same thing twice in different words.
