Root Breakdown

Root-derived
mainstay, remain, dwell
=main

The adjective 'main' (chief) is Germanic (Old English mægen, strength), a look-alike to the Latin manēre root of this family — flagged as same-spelling-different-origin.

Why It Means This

Caution: this everyday main ('main reason,' 'water main') is NOT from the root manēre. It comes from Old English mægen, meaning 'strength, power' — the same source as 'might.' The main thing was the strongest, most powerful thing. The root page lists this word because it shares the spelling main, but its origin is Germanic strength, not Latin 'stay.' A genuine false friend within the family.
