한

한

"한" is not Japanese; it is Korean, meaning "resentment," "grief," or "a deep, lingering sorrow."

Here, the word '一' corresponds to the Japanese word 'ひと' (hito) meaning one, similar to the Korean '한' which can represent the number one.

一つの空は広い。

The sky is vast.

In this sentence, '一部' uses '一' to denote a part or portion, demonstrating the meaning 'one' as in 'single'.

彼はあの映画の一部しか覚えていない。

He only remembers a part of that movie.

The word '一羽' consists of '一', indicating a single bird, matching the conceptual usage of '한' to mean one or single in Korean.

その箱には一羽の鳥が入っている。

There is one bird in that box.
