Root Explanation

Aligner → It is formed from "align" (from Old French *aligner*, meaning to line up) and "-er" (meaning a person or thing that performs an action). The word "aligner" refers to a person or device that aligns or arranges things in a straight line or proper position.

Memory Tip

Think of someone or something that helps to 'line up' — 'align' means to line up, and '-er' indicates a person or thing that does this.
