i find often even if you don't know the word, you know something about, for example, the phoneme structure of words, which allows you to guess.

it's not just it's not known, but also it has an uncommon composition.

for example, you may not know what the solution to abapi_al is exactly, but reasoning phoenetically should get it quickly.

Yeah I knew the concept but didn't know this word to describe it, good to find out these little things.
