よろしければ

The conditional form of よろしい, the polite equivalent of いい (good; alright). This expression softens requests, offers, and suggestions by explicitly giving the listener the option to decline. It is a hallmark of polite Japanese and is used extensively in customer service, business, and formal social interactions.

Usage

• Placed at the beginning of a sentence as a polite lead-in
• Often followed by polite request forms like ～ていただけますか or ～てください
• Can stand alone as a question: よろしければ？ (If that's alright?)

Register

• よければ: casual equivalent
• よろしければ: standard polite
• よろしかったら: slightly softer variant (also polite)
