按 vs 按照 vs 根据: basis coverbs for 'according to'
The coverbs 按 (àn), 按照 (ànzhào), and 根据 (gēnjù) all translate to 'according to' but differ in what they base the statement on. 按 and 按照 are used when following a rule, procedure, or standard, while 根据 introduces an evidential basis or source of information.
All three words function as coverbs meaning 'according to', but they are not interchangeable. 按 and 按照 are nearly synonymous, with 按 being more concise and often used in set phrases, while 按照 is more formal and used with longer expressions. Both indicate compliance with a rule, standard, or procedure. 根据, on the other hand, refers to the evidential basis or source of information, such as a report or data. Choosing the wrong one can change the meaning from 'following a rule' to 'based on evidence'.
Quando usar cada um
Use 按 when indicating that an action follows a rule, standard, procedure, or plan. It is often used in fixed expressions and with single-character nouns, but it also appears naturally with multi-character nouns. 按 is slightly less formal than 按照 but is common in both spoken and written Chinese.
按 is often preferred in set phrases like 按时 (on time) or 按计划 (according to plan).
Use 按照 to express following a rule, law, standard, or instruction. It is more formal and explicit than 按 and is typical with longer or more complex noun phrases, such as 按照学校的规定 (according to school regulations).
按照 can often be replaced by 按 in informal contexts, but 按 may sound unnatural with very long phrases.
Use 根据 to introduce the source, evidence, or factual basis for a statement or action. It is used with nouns like research, data, reports, or experiences. 根据 does not imply following a procedure but rather that the conclusion is drawn from information.
Unlike 按/按照, 根据 can function as a noun meaning 'basis' or 'foundation' (e.g., 有根据 'have basis').
