Root Breakdown

Native English
al-to, toward
+
lybind, tie
=ally

Despite sitting under the ali root here, ally actually comes from Latin alligare (ad- 'to' + ligare 'to bind') — to bind oneself to another. The connection to ali ('other') is a coincidence of spelling; the real root is lig ('bind'), the same as in ligament and league.

Root lig still carries 18 more words

Usage Guide

Stress shifts: the noun is usually AL-ly (/ˈælaɪ/), while the verb is often a-LLY (/əˈlaɪ/). 'Ally with / ally oneself to' for the verb; 'a close ally of' for the noun.
