お~になる (尊敬語 honorific verb form)

The productive 尊敬語 (sonkeigo) pattern お + verb-stem + になる, used to elevate a respected person's actions — 先生がお帰りになる ('the teacher is going home,' honorific), お待ちになる ('wait'), お読みになる ('read'). One of the two main honorific-verb patterns alongside lexical replacements. Parallel to humble お~する.
