Attune is formed from "ad-" (meaning to) and "tun" (from Old English *tun*, meaning enclosure or settlement). The word means to bring into harmony or to adjust to a particular condition, as if adjusting to the environment of a settlement.
Think of 'tuning' something to make it fit well — 'ad-' means to, and 'tun' relates to a place or condition. This helps you remember that attune means to adjust or harmonize.
