buckled
座屈した
解説 Definition
buckled は buckle(曲がる、座屈する、留め金で留める)の過去形・過去分詞です。ここでは、圧力などで部材が曲がって「座屈した」という状態を表します。
Bent, warped, or collapsed sideways after becoming structurally unstable under compression or another heavy force. In engineering contexts, it especially describes a beam, column, or support that has failed by buckling.
覚え方のコツ Memory Tip
原形 buckle の語末 e を取って -ed を付けた形で、発音は /ˈbʌkəld/。ここでは留め金で留めた意味ではなく、beam、column、support などが圧縮荷重に耐えられず横にたわんだ「座屈した」状態を表す。単なる bent より、構造部材が荷重で不安定化した工学的な響きが強い。
Connect buckled with the base verb buckle. The final silent e is removed before -ed is added, producing buckled, pronounced /ˈbʌkəld/; the ending does not create a separate /ɪd/ syllable. In this engineering sense, picture a straight column under a heavy compressive load suddenly bowing sideways. Common partners are buckled beam, buckled column, and buckled support. Bent is a broader everyday description, while buckled often suggests that a structural member lost stability under force. Keep this sense separate from buckled meaning “fastened with a buckle.”

buckled の語源・成り立ち Etymology
buckled は buckle からで、buckle は古フランス語 boucle「輪・留め金」を経てラテン語 buccula にさかのぼります。輪のように曲がる形の連想から、「押されてたわみ、座屈した」という意味が生まれました。関連語は boucle, buckler。
Buckled is the past tense and past participle of buckle. Buckle entered English through Old French boucle, meaning a ring or fastening, from Latin buccula. The verb first referred to fastening with a buckle. From the curved or crumpled shape associated with bending, it developed senses such as bend, collapse, or give way under pressure. Engineering uses buckled specifically for structural instability under compressive force.
