Source etymology 3

Original entry ↗
noun

A syllable used in solfège to represent the fifth note of a major scale. · Sometimes syllable for both the second and the fifth.

Selected source glosses provide context, not a complete modern definition inventory

Shortened from sol, to make it an open syllable for uniformity with the rest of the scale, from Glover's solmization, from Middle English sol (“fifth degree or note of Guido of Arezzo's hexachordal scales”), Italian sol in the solmization of Guido of Arezzo, from the first syllable of Latin solve (“wash away”) in the lyrics of the scale-ascending hymn Ut queant laxis by Paulus Deacon.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
