grammar point · tier 1 · 會 — likelihood / will (be likely to, probably will)
· huì
Predicts that an event is likely to come about — will, is going to, would (probably). Set before the verb to forecast the outcome, not the speaker's plan.

字源 FORM what the parts do

會 sets a lid (亼) down on a layered steamer (曾, written short): parts that fit together, the sense to join. Before a verb it forecasts the fit, the conditions falling into place for the thing to happen.

故事 STORY a scene to remember it by

The future is a stack of layers; the lid comes down and seats, and the thing arrives. When the lid will not seat, it stays away.

會2
Same character, two jobs. 會1 forecasts an event lining up (明天會下雨, it is likely to rain). 會2 reports a learned skill (我會游泳, I can swim). 會1 faces the world's odds; 會2 faces what you have mastered.
會 forecasts the world (他會來, he is likely to come). 要 announces a will or plan (他要來, he intends to come). 會 reads the odds; 要 states the intention.
negating with 沒: 我沒會去 → 我不會去 (unlikely / won't)
forecasting a plan instead of odds: 我會去(meaning I plan to)→ 我要去 (intention)
dropping 會 in the prediction: 明天下雨 → 明天會下雨 (it is likely to rain)
English 'will' fuses prediction and intention, so learners reach for 會 where a plan calls for 要, and for 要 where a forecast calls for 會.
