Source etymology 2

Original entry ↗

verb

To call in response to disturbance.

intj

The sound of a bird's call in response to disturbance.

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

Apparently onomatopoeic. Compare German gack (“call of a hen”), German gackern (“(of a chicken) to loudly and repetitive cry”), and Dutch gakken (“(of a goose) to honk”). Comparison to more terms Pokorny compared German gackern to words including English gaggle, Latvian gâgát (“cry like a goose”), Russian gogotátь (gogotátʹ, “(of geese) cackle; laugh loudly”), Old Norse gaga (“mock, ridicule”), and Albanian gogësínj (“yawn, burp”), among others. Pokorny considered common origin or separate innovation both as possibilities to explain the similarities.

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.
