What does 転勤になる mean?


Is it an abbreviation of 転勤することになる？ How is it different from just 転勤する？

Example: 父は京都支店へ転勤になりました

Is it similar to the humbleness of 結婚になりました！？




I assume you already know the [basics of how ことになる
works](https://apieceofsushi.com/jlpt-n4-grammar-koto-ni-
naru-%E3%80%9C%E3%81%93%E3%81%A8%E3%81%AB%E3%81%AA%E3%82%8B-%E6%84%8F%E5%91%B3-%E6%96%87%E6%B3%95-meaning/).

転勤することになりました normally refers to a future event (relative to the time of the
statement). "It was decided that (someone) **would** be transferred."

転勤になりました can also refer to a future event, in which case the two sentences are
interchangeable. But 転勤になりました can be used also to refer to a past event, like
"(Someone) was transferred (following someone's decision)". So 先月転勤になりました
usually means this person was actually transferred last month, whereas
先月転勤することになりました usually means such a decision was made last month (but the
actual transfer may happen much later).

Note that `noun + になる` works like this only when the noun is inherently
related to some decision/judgement (有罪, 合格, 採用, 離婚, etc.). Otherwise, `noun +
になる` may mean something different. For example, 勉強することになりました means "(It was
decided that) I am going to study", whereas 勉強になりました normally means "I learnd
a lot / It was a good lesson".
