差（さ、sa）
- difference

The Japanese word 差, pronounced さ (sa), carries a variety of meanings, primarily relating to "difference," "discrepancy," "variation," "margin," or "distinction." It can also refer to "to differ," "to make a difference," or "to give a margin." The specific meaning depends heavily on the context in which it is used. The core idea is about a gap, a contrast, or a variance between two or more things. It can be a noun or, less commonly, a verb. The kanji 差 itself depicts a hand holding something apart, visually conveying the notion of separation or difference. It is also used in compound words with other kanji to create more specific meanings.
