the.com/forbear

means To hold yourself back from doing or saying something, especially when restraint takes real effort.

from From Old English forberan, stitching together 'for-' (an intensifying or negating prefix, as in forbid or forgo) with 'beran,' meaning 'to bear or carry.' So literally it's 'to bear up against' or 'carry away from' — the same root sense behind 'bear' as in enduring a burden. The idea is old and physical: you're carrying the urge to snap back, and choosing not to set it down on someone else.
