一概 vs 一律 (yīgài vs yīlǜ): abstract generalization vs. uniform standard
一概 and 一律 both mean 'without exception,' but 一概 is used for abstract generalizations (often negative) about knowledge, opinions, or categories, while 一律 describes uniform rules, treatments, or states applied uniformly to a group. Use 一概 with verbs like 否定 'deny' or 不知 'not know', and 一律 with regulations like 禁止 'prohibit' or requirements like 要求 'require'.
Both 一概 and 一律 are adverbs that mean 'without exception' or 'all alike', but they operate in different domains. 一概 generalises across abstract concepts, often carrying a negative connotation of blanket rejection or ignorance (e.g., 一概否定 'categorically deny'). 一律 emphasises uniformity in rules, standards, or treatments applied equally to every member of a group (e.g., 一律禁止 'uniformly prohibited'). Choosing the wrong one can sound unnatural: using 一律 for abstract opinions or using 一概 for official regulations would be incorrect. The fixed phrase 一概而论 (make sweeping generalizations) is a notable exception where 一概 is used with a verbal complement.
When to use each
Use 一概 when making a broad, abstract generalization that covers all cases, especially with verbs of denial, ignorance, or opinion (e.g., 否定, 不知, 而论). It is typical in written or formal Chinese and often appears in negative statements. For example: '他一概否定我的意见' (he categorically denied my opinion).
一概 is almost exclusively used with negative predicates or in a negative sense; positive uses are rare. It does not imply a rule or regulation, but rather a mindset or categorical statement.
Use 一律 when describing a uniform rule, standard, or treatment that applies to all members of a group without exception. Common contexts include official regulations, dress codes, procedural requirements, and uniform states (e.g., '一律禁止' 'uniformly prohibited', '服装一律' 'uniform clothing'). It often accompanies verbs like 禁止, 通过, 实行, or 要求.
一律 can be used in both positive and negative statements, but always implies an authoritative or fixed rule. It is common in legal, administrative, and formal instructions.

Common mistakes
- Using 一律 for abstract knowledge: ✗ '我一律不知' — should be 一概不知.
- Using 一概 for official rules: ✗ '一概禁止吸烟' — should be 一律禁止吸烟 (unless in an abstract opinion context).
- Assuming they are always interchangeable: they are not; 一概 focuses on opinion, 一律 on regulation.
- Using 一概 in positive statements like '一概通过' — unnatural; use 一律通过 for 'all pass uniformly'.
- Forgetting the fixed phrase 一概而论: writing '一律而论' is incorrect.
FAQ
- When do I use 一概 vs 一律?
- Use 一概 when making a broad, often negative generalization about knowledge, opinion, or attitude (e.g., 一概不知 'know nothing'). Use 一律 when describing a uniform rule or treatment that applies to every member of a group (e.g., 一律禁止 'uniformly prohibited').
- Can 一概 and 一律 be used interchangeably?
- No. They belong to different semantic domains: 一概 generalises abstractly, while 一律 enforces uniformity by rule. In very rare contexts (e.g., 'all are the same') some overlap exists, but even then nuance differs. Always check if you are expressing a subjective summary (一概) or an objective regulation (一律).
- What does 一概而论 mean?
- 一概而论 is a fixed idiom meaning 'to make sweeping generalizations' or 'to treat different things as the same'. It is always used with 一概, never 一律. Example: '不能一概而论' — 'you can't paint everything with the same brush'.
- Is 一律 more formal than 一概?
- Both are formal, but 一律 is strongly associated with official, legal, and administrative language, while 一概 is more common in written arguments, opinions, and literary contexts. 一概 is slightly less formal than 一律, but still not used in casual conversation.
