Synonyms & Differences 近义词辨析
Compared meaning: to wound someone with something sharp (verb).
比较义项：用刀或尖锐物刺伤某人（动词）。
- knife 本词
Knife specifically means to wound someone using a knife as the weapon; it often appears in news reports and sounds factual rather than dramatic.
knife特指用刀这种凶器伤人，常出现在新闻报道中，语气比较客观、正式，不太带感情色彩。
The reporter said the victim was knifed outside the nightclub last night.
据记者报道，受害者昨晚在夜店外被人knifed。
- stab
Stab describes a sudden, forceful thrust with any sharp object, not necessarily a knife, emphasizing the violent piercing motion itself.
stab表示用尖锐物迅猛地刺入某人或某物，不一定是刀，强调的是突然而有力的刺戳动作本身。
In a panic, he grabbed a screwdriver and stabbed the attacker's arm.
他惊慌中抓起一把螺丝刀，狠狠地stab了攻击者的手臂。
Knife and stab both mean to wound with something sharp. Knife means using a knife, sounding factual, common in news reports. Stab means a sudden, forceful thrust with any sharp object, stressing violent action. Not compared: knife as a noun, or stab meaning 'an attempt'.
这两个词都表示用尖锐物伤人，但knife特指用刀作案，语气偏客观，常见于新闻报道；stab不限于刀，强调猛力刺入的动作本身，使用范围更广，也可用于物体（如刺西红柿）。这里不比较knife作名词表示“刀”的用法，也不比较stab表示“尝试”（a stab at doing something）的用法。
