お～だ (respectful description)

• Reading: お
• Romaji: o ~ da
• Formation: お + Verb ます-stem + だ/です

Meaning

A respectful expression used to describe another person's action or state with deference. It wraps the verb ます-stem with the prefix お and the copula だ/です.

The pattern お + Vます-stem + だ/です is an honorific descriptive form that shows the speaker's respect when talking about someone else's actions or states. It is softer than the full honorific お～になる and is commonly used in daily polite speech. For example, お帰りですか (Are you heading home?) is a respectful way to inquire about someone's departure. This form is distinct from お～する, which is humble (used for one's own actions). The pattern is limited to native Japanese (和語) verbs; Sino-Japanese verbs use ご instead of お. It is not used to describe one's own actions.

Examples

1. 社長はもうお帰りですか。 Is the company president heading home already?
2. 先生はお忙しいようです。 The teacher seems to be busy.
3. 部長がお読みの資料はこちらです。 The documents the department head is reading are here.
