the.com/insistence

means The act of pressing a demand or claim again and again until it's acknowledged or granted.

from From Latin insistere — 'to stand upon, persist, dwell on' — built from in- ('upon') plus sistere ('to stand, take a stand'), itself a relative of stare ('to stand'). The image buried in the word is literal: insisting is standing your ground on a point, refusing to step off it, and planting your feet there again every time someone tries to walk you away.
