lean

Compared meaning: thin in body (adjective).

比较义项：瘦的（形容词，指人或动物体型偏瘦）。

• lean 本词

  Lean stresses having little fat and often implies muscularity or fitness; typically describes athletes, meat, or a fit build, with a positive or neutral tone.

  lean强调脂肪少，常暗示健壮或健美，多用来形容运动员、瘦肉或健康的体型，语气中性偏褒义。

  After months of training, the boxer had a lean, muscular body.

  经过几个月的训练，这位拳击手拥有精瘦而结实的身体。

• thin

  Thin is the neutral, general word for low body fat, without implying either good health or muscle; it simply states body size, more plainly than the others.

  thin是中性、笼统的说法，表示体脂低，不暗示健康或肌肉，只是单纯陈述体型大小，语气比其他几个词更平淡。

  She's naturally thin, but she eats a lot every day.

  她天生很瘦，但她每天都吃很多东西。

• skinny

  Skinny means very thin, often informally, and can sound critical or negative, suggesting someone looks too thin or unhealthy rather than fit.

  skinny表示很瘦，语气较口语化，常带贬义，暗示某人瘦得过分或不健康，而不是健美。

  He was so skinny after the illness that his ribs were visible.

  他生病后瘦得连肋骨都看得见。

• slender

  Slender combines thinness with grace and elegance, giving a flattering, often literary tone; it typically describes a woman's figure or a delicate build, not a muscular body.

  slender把瘦和优雅结合在一起，语气带有褒义和文学色彩，多用于形容女性的身材或纤细的体态，而不是肌肉发达的身体。

  The ballerina moved with grace, her slender arms extended gracefully.

  这位芭蕾舞演员优雅地移动，纤细的手臂舒展自如。

Lean, thin, skinny and slender all describe a thin body, with different tones. Lean suggests fitness or muscle. Thin is neutral and general. Skinny sounds negative. Slender adds grace, often for a woman's figure. This excludes lean as a verb, and slender meaning 'small amount'.

这四个词都表示“瘦”，语气和感情色彩不同：lean多指健美、有肌肉的瘦；thin最中性笼统；skinny口语化，常带贬义；slender强调优雅纤细，语气偏褒义。这里不比较lean作动词表示“倚靠”的义项（如lean against the wall，倚靠墙壁），也不比较slender表示“微薄的”的义项（如slender income，微薄的收入）。

Compared meaning: a leaning or sloping position (noun).

比较义项：倾斜（名词）。

• lean 本词

  Refers to a body or object resting at an angle against something, often implying support or contact; commonly used with 'against' or 'on'.

  指身体或物体以一定角度倚靠在某物上，常暗示有支撑或接触；常与介词 against 或 on 搭配使用。

  He likes to lean against the wall while waiting.

  他喜欢等待时倚靠在墙上。

• tilt

  Refers to a change in angle or a sloped position, often momentary or adjustable, without implying contact with a support; used for heads, objects, or surfaces.

  指角度的改变或倾斜的位置，常是暂时性或可调整的，不暗示有支撑物接触；可用于头部、物体或表面。

  She had to tilt her head to see the sign clearly.

  她不得不歪头才能看清那个标志。

Lean and tilt both describe an object away from vertical or horizontal. Lean stresses a body or object resting against something, often with 'against' or 'on'. Tilt stresses a change in angle, without implying support. This does not compare lean meaning 'to tend toward'.

两者都指物体偏离垂直或水平位置的状态，但 lean 强调整体身体或物体倚靠、依偎的姿态，常带方向性（靠向某物）；tilt 强调角度上的倾斜或偏转，不一定有依靠的对象。这里不比较 lean 的其他引申义（如“倾向于”）。
