解説 Definition
矛盾する、相反する、または一貫性がない状態を表します。意見や行動が互いに一致しないことを指す場合が多いです。
Inconsistency is a situation where parts of something do not match or agree with each other. It is often used when facts, statements, behavior, or quality change in a way that seems uneven or contradictory. This word is common in writing, research, and discussions of logic or standards.
覚え方のコツ Memory Tip
まず simpler な consistent「一貫した」を軸に覚えるとよい語です。consistency が「一貫性」、そこに否定の in- が付いて inconsistency で「一貫していないこと」。話・態度・データが前と後で食い違う場面を思い浮かべると定着します。inconsistency in the story / data の形でよく出ます。contradiction がはっきりした「矛盾」なのに対し、こちらは「ぶれ・不一致・ちぐはぐさ」まで含めて広く使えます。
Break it into `in-` + `consist` + `-ency`. `Consist` is about parts fitting together, so `inconsistency` is when they do not fit. Remember common patterns like `an inconsistency between A and B` or `detect an inconsistency in his story`.

inconsistency の語源・成り立ち Etymology
ラテン語 consistere「しっかり立つ・まとまる」に由来し、in-「否定」+ consist「成り立つ」+ -ency「性質」でできた語。もともと「一つに落ち着いていない状態」なので、話や行動が食い違う「矛盾・不一致」の意味になる。関連語は consistent, consist。
"Inconsistency" comes from Latin roots: "in-" meaning "not," plus "consistere," meaning "to stand firm" or "hold together." It came into English through "consist" and "consistent," with "-ency" added for a state or quality. The idea developed from "not holding together" to the sense of things not matching or staying in agreement.
