覚え方のコツ Memory Tip
sus は suspicious「怪しい」を短くしたくだけた俗語で、オンライン会話やゲームの場面と結び付けます。pure sus、too much sus のように名詞なら「怪しさ・怪しいもの」、形容詞的なら That looks sus.「それ怪しい」と使われます。正式な文章では suspicion や suspicious に戻す、と使用域ごと覚えるのが実用的です。
Sus is a clipped form associated with suspicious, so its first three letters provide the memory link. Picture players in an online social-deduction game noticing behavior that does not add up and calling it sus. In noun-like expressions such as pure sus or too much sus, it refers to suspiciousness or something suspicious; in everyday slang, people also say “That looks sus,” using it like an adjective. The important contrast is register: sus is short, playful, and highly informal, while suspicious and suspicion are appropriate in neutral or formal contexts. Remember both the meaning and the setting in which the shortened form sounds natural.

sus の語源・成り立ち Etymology
「sus」は「suspicious（怪しい）」を切り詰めた現代の略語です。語源はラテン語の「sub-（下から）」＋語根「spec（見る）」にあり、下から警戒してこっそり覗き見る態度が「疑わしい」という意味に発展しました。同じ語根を持つ関連語にinspect（検査する）があります。
Sus is a modern clipped form associated chiefly with suspicious, and sometimes with suspect. Both longer words ultimately belong to a Latin family built around specere, “to look,” with the prefix sub-. The slang form became especially visible in digital conversation and online gaming, where speed and brevity favor shortened expressions. Its popularity increased through social-deduction games, but the abbreviation itself predates that trend. Because its grammar is flexible in slang, it may function as a noun or adjective-like expression.
