Sense: verb/1
All three words describe ways of smiling, but they differ in width, emotion, and connotation. 'Grin' is a very wide smile that often shows your teeth, used when you are extremely pleased or amused ('Theo grinned from ear to ear when he won the prize'). 'Beam' suggests a bright, radiant smile that lights up the whole face, usually from deep happiness or pride ('Maja beamed as she accepted the award'). 'Smirk' has a narrower, more controlled smile that tilts to one side, suggesting self-satisfaction or secret knowledge, often in a way others find irritating ('He smirked at his classmate's mistake'). For a regular, neutral expression of friendliness or pleasure, use 'smile'.
