Stab, poke, prod, and jab all mean to poke sharply. Stab is strongest, a forceful, risky thrust with something sharp. Poke is lightest, a gentle finger touch, for attention. Prod means a repeated poke urging movement. Jab means a quick, sharp thrust, as in boxing.

这几个词在戳、刺这一动作上意思相近，但语气强弱和使用场合不同：stab 语气最重，多指用刀等尖锐物用力刺入，带有暴力或危险的意味；poke 最轻，常指用手指轻轻一戳，多用于引起注意或开玩笑；prod 强调反复或带催促意味地戳，常用于催促行动迟缓的人或动物；jab 强调动作快而有力，常见于拳击等场景。这里不比较 stab 作名词表示尝试（have a stab at）、jab 在英式英语中表示打针、prod 作名词表示赶牛用的刺棒等其他用法。
