deliberate

Compared meaning: done on purpose, not by accident (adjective).

比较义项：故意的，经过考虑而非偶然发生的（形容词）。

• deliberate 本词

  Emphasizes careful thought or slow, controlled action before or during doing something; often describes a considered decision, or a slow, careful manner (a deliberate pace); neutral to positive tone.

  强调事前经过深思熟虑，或动作缓慢、从容、有控制感；常用来形容经过考虑的决定，或描述从容不迫的方式（如 deliberate pace，从容的步伐）；语气中性偏褒。

  He spoke in a slow, deliberate voice so that everyone in the room could follow.

  他用缓慢而从容的语气说话，好让房间里的每个人都能听懂。

• calculated

  Emphasizes strategic planning aimed at producing a specific effect, often for personal advantage; frequently used for risks, insults, or moves, and can carry a negative, scheming connotation.

  强调为达到特定效果而进行的策略性谋划，常是为了自身利益；多用于形容风险、侮辱或举动，带有算计、城府较深的负面意味。

  It was a calculated risk, but investing early gave the company a real advantage.

  这是一次经过精心盘算的冒险，但提前投资确实给公司带来了真正的优势。

• intentional

  The plainest, most neutral word; simply means done on purpose rather than by accident, without implying careful planning or strategy; common in everyday talk about actions or behavior.

  是最普通、语气最中性的词，只是表示“故意做的，而非意外发生”，不含深思熟虑或策略谋划的意味，日常谈论行为或动作时最常用。

  His rude comment felt intentional, not just a careless mistake.

  他那句无礼的话让人觉得是故意的，而不只是一时疏忽。

All three mean done on purpose, not by accident. Deliberate means careful thought or slow, controlled action, not its verb sense, to discuss carefully. Calculated means strategic planning for an effect, scheming, not calculate meaning to compute. Intentional is the plainest word, meaning not accidental.

这三个词都表示“故意做某事，而非偶然”，但语气和用法有所不同：deliberate 强调事前经过深思熟虑、动作从容不迫；calculated 强调为达到特定效果而精心策划，常带负面或算计的意味；intentional 是最普通、语气最中性的说法，只是强调“并非意外”。这里不比较 calculate 的“计算”义（如计算费用），也不比较 deliberate 作动词“仔细商议”的用法。

Compared meaning: slow and unhurried (adjective).

比较义项：从容不迫、不慌不忙（形容词）。

• deliberate 本词

  Describes a slow, careful, controlled manner, often of movement or speech, that suggests caution or deliberateness rather than relaxation; commonly used with steps, pace, or voice.

  形容动作或说话缓慢、谨慎、有控制的从容，强调刻意和克制，而非放松；常用来修饰脚步、步伐或语调。

  He crossed the icy pavement with slow, deliberate steps.

  他迈着缓慢而从容的脚步走过结冰的人行道。

• leisurely

  Describes an unhurried pace taken for comfort, relaxation or enjoyment, with no sense of urgency or control; typically used with walks, meals, mornings, or other relaxed activities.

  形容为了舒适、放松或享受而放慢节奏的从容，没有紧迫感，也不强调克制；常用来修饰散步、用餐、早晨等休闲活动。

  They took a leisurely walk along the beach at sunset.

  他们在日落时沿着海滩悠闲地散步。

Both words describe something slow and unhurried. Deliberate describes a careful, controlled manner, of movement or speech, suggesting caution (not its other sense, done on purpose or planned). Leisurely describes an unhurried pace taken for comfort or enjoyment, with no sense of caution, just relaxation.

这两个词在“从容不迫”这一义项上意思相近，但语气不同：deliberate强调动作或语调缓慢而有控制，带着谨慎、刻意的意味；leisurely则强调因放松、享受而不慌不忙，语气更轻松惬意。这里不比较deliberate表示“经过深思熟虑的、故意的”这一义项。

Compared meaning: to think carefully about something (verb).

比较义项：仔细考虑，权衡（动词）。

• consider

  Consider is the common, general word for thinking about something before deciding; it is transitive and used in everyday and formal contexts, often followed directly by a noun or -ing clause.

  consider 是最常用、最普遍的表示“仔细考虑”的动词，及物，用于日常和正式场合，后面可直接接名词或动名词。

  Please consider my proposal carefully before our meeting tomorrow.

  请在我们明天开会之前，仔细考虑一下我的提案。

• deliberate 本词

  Deliberate suggests careful, unhurried, often formal thought about an important matter, and is typically used intransitively, as in deliberate about or over something, rather than with a direct object.

  deliberate 强调对重要事情进行缓慢、仔细、往往较为正式的思考，通常用作不及物动词（deliberate about/over……），很少直接接宾语。

  The jury deliberated for six hours before reaching a verdict.

  陪审团经过六个小时的仔细商议后才做出裁决。

Both words mean thinking carefully about something. Consider is common and general, taking a direct object (not its other sense, to regard or view something as). Deliberate suggests slower, more formal thought, used without a direct object (not its adjective sense, done on purpose).

这两个词在“仔细考虑”这个意义上很接近，但 deliberate 语气更正式，强调对重要事情进行缓慢、慎重的思考，且通常用作不及物动词；consider 更常见、更中性，直接接宾语。这里不比较 deliberate 作形容词表示“故意的，蓄意的”的用法，也不比较 consider 表示“认为，把……看作”的用法。
