What is a word for live or reside; to keep thinking about?

Dwell.

@syz too good.

lodge, perch, squat

fluth.

j/k

@syz or @AstroChuck probably nailed it, but another is abide.

“Dwell” is the only word that also means to keep thinking about. So syz gets the gold.

Gail is right (as is syz, of course). It has to be dwell. I hadn’t noticed that the question mentioned to keep thinking about.
There you go, tilesha. You can now finish that crossword puzzle.

@AstroChuck… I am similarly guilty
