British vs American Usage
Differences
Usage is largely identical. Slightly more common in British English in the idiom 'wag one's finger' as a gesture of admonishment.
Connotations
Playful, scolding, or rhythmic motion. In British slang, 'wag' can also mean to play truant (as in 'play the wag'), but this is archaic/regional.

Moderately common in both varieties. Higher frequency in contexts involving pets (tails) and humorous/scolding human gestures.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'взгромождаться' (to clamber) or 'мешок' (sack). The Russian verb 'вилять' (to wiggle, to dodge) is a closer match for the motion sense.
Common Mistakes
- Using 'wag' for slow, heavy movements (use 'swing'). Confusing 'wag' (playful) with 'waggle' (more unsteady). Incorrect past tense 'wagged' (not 'wug').
