規定

That's a good question! While both 規定 (kitei) and 規則 (kisoku) can be translated as 'rules,' there's a subtle but important difference in their nuance.

規定 (kitei) often refers to specific, detailed stipulations or provisions, usually formally established and legally binding. Think of it as a set of defined conditions or articles that govern a particular situation or system. It's about what is specifically stipulated or provided for.

規則 (kisoku), on the other hand, is a more general term for rules or regulations. It often refers to a broader set of guidelines, customs, or principles that dictate behavior or procedures. It's about what is generally required or expected.

So, you might have 会社の規則 (kaisha no kisoku - company rules) which are general guidelines, but within those, there might be 勤務時間に関する規定 (kinmu jikan ni kansuru kitei - regulations regarding working hours) which are very specific details.

Generally, no. 規定 (kitei) has a more formal and official feel to it. It's usually used for regulations set by organizations, governments, or institutions. For household rules, you'd more likely use 規則 (kisoku) or even simply ルール (rūru - rule). So, while you could technically say 家庭の規定 (katei no kitei), it would sound quite stiff and unnatural. Stick to 規則 or ルール for informal settings.

Yes, almost always. Because 規定 (kitei) refers to specific stipulations and provisions, they are almost invariably written down. They form part of a legal document, a company policy, or an official set of guidelines. It's not something that's usually just understood or informal.

Certainly! Here are a couple of examples:

この会社の規定では、副業は禁止されています。
Kono kaisha no kitei de wa, fukugyou wa kinshi sarete imasu.
(According to this company's regulations, side jobs are prohibited.)

法律の規定に従って行動しなければならない。
Hōritsu no kitei ni shitagatte kōdō shinakereba naranai.
(You must act in accordance with the law's provisions.)

規定 (kitei) is definitely on the more formal side. You'll encounter it often in business settings, legal documents, news, or when discussing official procedures. In casual daily conversation, you're less likely to hear it. For everyday 'rules,' 規則 (kisoku) or ルール (rūru) are much more common.

Yes, it can! When used as a verb, it becomes 規定する (kitei suru), meaning 'to stipulate,' 'to provide for,' or 'to prescribe.' For example:

契約書には、罰則が規定されています。
Keiyakusho ni wa, bassoku ga kitei sarete imasu.
(Penalties are stipulated in the contract.)

新しい法律で、上限が規定されました。
Atarashii hōritsu de, jōgen ga kitei saremashita.
(An upper limit was prescribed by the new law.)

規定 (kitei) typically refers to very specific details. Think about:

• 労働時間に関する規定 (rōdō jikan ni kansuru kitei): Regulations regarding working hours
• 安全に関する規定 (anzen ni kansuru kitei): Safety regulations
• 利用規約の規定 (riyō kiyaku no kitei): Provisions in the terms of service
• 試験の規定 (shiken no kitei): Examination stipulations (e.g., what you can bring, time limits)

Absolutely! Breaking down the kanji can definitely help.

規 (ki) means 'rule,' 'measure,' 'standard.' It implies setting a standard or a framework.

定 (tei) means 'fix,' 'settle,' 'decide.' It implies something being determined or established.

So, together, 規定 (kitei) literally suggests 'to fix a rule' or 'a fixed rule,' which aligns perfectly with its meaning of specific, established regulations or provisions.

For a general policy, 規定 (kitei) might be too specific. You'd typically use 方針 (hōshin) for 'policy' or 政策 (seisaku) for 'government policy.' 規定 (kitei) would refer to the very detailed rules or stipulations that implement or are part of that broader policy. So, the policy sets the direction, and the 規定 (kitei) are the specific rules to follow that direction.

A common mistake is using 規定 (kitei) when a more general word like 規則 (kisoku) or even ルール (rūru) would be more appropriate. Because 'regulation' or 'stipulation' can sound quite broad in English, learners sometimes apply 規定 (kitei) to general rules.

Remember, 規定 (kitei) is for specific, often formal, and detailed provisions. If you're talking about something less formal or more general, opt for 規則 or ルール. Always consider the formality and specificity of the 'rule' you're trying to convey.
