〜かたがた

〜かたがた is a high-level formal expression (JLPT N1 level) used to express that a single physical action is performed to accomplish two purposes. Importantly, 〜かたがた combines these two purposes in a highly formal manner, emphasizing social etiquette and respect. It carries a strong nuance of social obligation and politeness. Grammatically, the preceding noun represents the primary purpose. However, as a pragmatic business strategy, it is often used as a polite excuse to show consideration, while the following verb represents the actual main business, or both carry equal weight.

Key Characteristics:

• Register & Orthography: It is strictly formal and almost exclusively written in hiragana. You will see it in business emails, formal letters, or hear it during ceremonial speeches. It is often used in closing phrases like 「お礼かたがたご挨拶まで」（おれいかたがたごあいさつまで - A brief greeting to also serve as my thanks）. In this specific letter-closing format, the main verb (e.g., 申し上げます) is completely omitted and replaced by 「〜まで」. In written communication, the physical action accomplishing the two purposes is often the very act of writing or sending the message itself. Unlike 〜がてら or 〜ついでに, 〜かたがた leans formal, but it does appear with everyday actions such as 散歩かたがた (while out for a walk), where it lends an old-fashioned, literary tone.
• Connection: It attaches directly to nouns without the particle の (e.g., it is always お礼かたがた, never お礼のかたがた). Crucially, when attaching to a verbal noun (suru-verb), the する must be dropped (e.g., 報告かたがた, never 報告するかたがた). Furthermore, unlike 〜がてら or 〜ついでに, it cannot attach to conjugated verbs. Additionally, nouns naming a social duty usually take the polite prefix お or ご (お礼, ご挨拶), while event and movement nouns stand on their own (出張かたがた, 帰省かたがた, 報告かたがた).
• Focus: It frequently attaches to action nouns related to social duties, such as お礼（おれい - thanks）, ご挨拶（ごあいさつ - greeting）, お見舞い（おみまい - visiting the sick）, or お詫び（おわび - apology）. It is also used with other formal event and movement nouns such as 報告（ほうこく - report）, 出張（しゅっちょう - business trip）, 帰省（きせい - homecoming）, and 墓参り（はかまいり - visiting a grave）.
• Following Verbs: The main verb following this pattern is almost always a verb of movement (e.g., 伺う, 参る) or a verb of communication (e.g., 申し上げる, お知らせする). Because the subject is usually the speaker, these verbs are typically in their humble form (謙譲語), such as 伺う（うかがう） or 申し上げる（もうしあげる）.
• Context & Restriction: It is used in formal social interactions, such as with clients, teachers, or in ceremonial settings. Most often it describes the speaker's own actions (or their in-group), which is why the verb is usually humble. It can also address the listener in a polite suggestion, as in ご出張かたがた、ぜひ京都を観光なさってください (While you are there on business, do please see Kyoto). What it does not do is describe a third party carrying out a social duty, so ❌「彼はお礼かたがたご挨拶に来てくれました」 is incorrect.

Unlike 〜ついでに, which is for casual 'while you are at it' moments, or 〜がてら, 〜かたがた is distinguished by its high formality and focus on social etiquette.
