Specifically refers to the remaining items or people from a previously defined set. It's an adjective.

More general, can mean 'another,' 'different,' or 'else.' Can be an adjective or an adverb.

A noun meaning 'the rest' or 'remainder.' Can be used independently or with a possessive suffix.

Both 'digar' and 'sāyer' can mean 'other.' However, 'digar' often implies 'another' or 'more' in a sequential sense, or 'different' in a general sense.

'سایر' (sāyer) specifically refers to 'remaining' or 'the rest' from a defined set. 'دیگر' (digar) is more general and can mean 'another,' 'different,' or 'else.'

افراد دیگر هنوز نرسیده‌اند. (Afrād-e digar hanūz narasīdand.) = Other people haven't arrived yet. (General 'other' people). سایر افراد هنوز نرسیده‌اند. (Sāyer-e afrād hanūz narasīdand.) = The remaining people haven't arrived yet. (Specific group of people who are left.)

Both 'baghiye' and 'sāyer' refer to 'the rest' or 'remaining.'

'بقیه' (baghiye) is a noun meaning 'the rest' or 'remainder.' 'سایر' (sāyer) is an adjective meaning 'other' or 'remaining' and needs to modify a noun.

بقیه پول را به من بدهید. (Baghiye-ye pūl rā be man bedahīd.) = Give me the rest of the money. (Here 'baghiye' is a noun). سایر دانش‌آموزان به اردو رفتند. (Sāyer-e dānesh-āmūzān be ordū raftand.) = The other/remaining students went on a trip. (Here 'sāyer' modifies 'students'.)

Similar to 'baghiye,' 'mābāqi' also means 'the remainder' or 'the rest.'

'مابقی' (mābāqi) is a noun, often used in more formal contexts, meaning 'the remainder.' 'سایر' (sāyer) is an adjective meaning 'other' or 'remaining.'

مابقی غذا را به فقرا دادیم. (Mābāqi-ye ghazā rā be foqarā dādim.) = We gave the remainder of the food to the poor. (Here 'mābāqi' is a noun). سایر شرکت‌کنندگان هنوز نرسیده‌اند. (Sāyer-e sherkat-konandegān hanūz narasīdand.) = The other/remaining participants haven't arrived yet. (Here 'sāyer' modifies 'participants'.)

While 'motafāvet' means 'different,' learners might sometimes confuse it with 'sāyer' when thinking about things that are not the same.

'متفاوت' (motafāvet) explicitly means 'different' in nature or kind. 'سایر' (sāyer) means 'other' or 'remaining' from a specific group, implying they are similar in type but just not the ones previously mentioned.

این دو کتاب کاملاً متفاوت هستند. (In do ketāb kāmelan motafāvet hastand.) = These two books are completely different. (Referring to their nature). سایر کتاب‌ها را کجا گذاشتی؟ (Sāyer-e ketābhā rā kojā gozāshtī?) = Where did you put the other/remaining books? (Referring to the rest of the books of the same type).

This phrase literally means 'the rest of the cases/items,' which conveys a similar meaning to 'سایر' when used with plural nouns.

'بقیهٔ موارد' (baghiye-ye mavāred) is a noun phrase. 'سایر' (sāyer) is a single adjective that can replace 'بقیهٔ' (baghiye-ye) before a plural noun to achieve a similar meaning of 'the remaining' or 'the other.' 'سایر' is more concise.

بقیهٔ موارد را بعداً بررسی می‌کنیم. (Baghiye-ye mavāred rā ba'dan barresī mīkonīm.) = We will review the rest of the items later. (Noun phrase). سایر موارد را بعداً بررسی می‌کنیم. (Sāyer-e mavāred rā ba'dan barresī mīkonīm.) = We will review the other/remaining items later. (Using the adjective 'sāyer').
