Root Explanation

Attester is formed from "ad-" (meaning to) and "testari" (meaning to witness or testify). The word refers to someone who witnesses or provides evidence for something, thus affirming its truth or validity.

Memory Tip

Think of someone who 'witnesses' ('testari') something and is 'to' ('ad-') affirming it — that's why an attester is someone who provides testimony.
