BIRD, BEIRD, BRID, BURD, s.
1. A lady, a damsel.
Gawan and Gol.
As bridde is the word used by Chaucer for bird, it is merely the A. S. term for pullus, pullulus. Bird, as applied to a damsel, appears to be the common term used in a metaph. sense.
2. Used, also metaph., to denote the young of quadrupeds, particularly of the fox.
V. [Tod's Birds].
BYRD, v. imp. It behoved, it became.
Barbour.
A. S. byreth, pertinet. This imp. v. may have been formed from byr-an, ber-an, to carry, or may be viewed as nearly allied to it. Hence bireth, gestavit; Germ. berd, ge-baerd, id., sich berd-en, gestum facere. Su. G. boer-a, debere, pret. borde, anciently boerjade.
BIRDING, s. Burden, load.
V. [Birth, Byrth].
Douglas.
A. S. byrthen, Dan. byrde, id.
