IPA: /əˈfɪksər/
KK: /əˈfɪksər/
A person or thing that attaches or fastens something to another object.
The affixer applied the label to the package before shipping.
Affixer is formed from "ad-" (meaning to) and "figere" (meaning to fix or attach). The word describes the act of attaching something to another object or surface.
Think of 'attaching' something ('ad-') firmly ('figere') — that's what affixer means.
