if it is possible
Polite, formal expression used to preface a request or suggestion, equivalent to できれば or 可能であれば but more literary and humble. Often seen in business or official contexts.
If it is possible, I would appreciate it if you could attend next week's meeting.
If possible, I would be grateful if you could reply early.
Formal but still less literary than 相なるべくは. 相なるべくは carries a humble, old-fashioned politeness.
Standard kanji spelling for this polite expression.
Variant spelling with 成る written out.
Rarely used kanji form with 可く for べく.
Derived from the humble prefix 相 (あい) + なる (to become) + べく (archaic adverbial form of べし, indicating possibility or obligation) + は (topic particle). The exact historical development is uncertain, but it functions as a set phrase meaning 'if it is possible'.
