覚え方のコツ Memory Tip
twitching は原形 twitch に -ing を付けた現在分詞・動名詞で、語末を変えずに作ります。まぶたや筋肉が意思とは無関係に一瞬ずつ「ぴくっ」と動く場面を結び付け、an eyelid is twitching、a muscle twitching の形で覚えましょう。shaking より動きが小さく急なのが特徴です。
Link twitching with a tiny, sudden pull in a muscle. Picture an eyelid moving in short, involuntary bursts: it is not a broad movement like shaking, and the person is not choosing to do it. Common subjects include an eyelid, hand, leg, or muscle. Grammatically, twitching is made by adding -ing to twitch with no spelling change. The base ends in the consonant cluster /tʃ/, so no final consonant is doubled. Remember the useful patterns my eyelid is twitching and a muscle twitching in my leg.
例文
My eyelid is twitching today.
今日はまぶたがぴくぴくしています。
His hand was twitching after the long practice.
長い練習のあと、彼の手はけいれんしていました。
She noticed a muscle twitching in her leg.
彼女は脚の筋肉がぴくぴく動いているのに気づきました。

twitching の語源・成り立ち Etymology
twitching は古英語 twiccian「ぐいとつまむ・引く」に由来し、ゲルマン系で「素早くつねる」感覚をもつ語です。語幹 twitch に進行・動名詞の -ing が付いた形で、ぴくっと引かれる感じから「けいれん」と納得できます。関連語は tweak, twinge。
Twitching consists of twitch and the suffix -ing, which marks a present participle or gerund. Twitch is related to Old English twiccian, a verb meaning to pluck, pull, or jerk sharply. The physical image of a quick pull developed naturally into the sense of a brief, sudden movement of a muscle or body part. The modern form preserves that central idea of a small, sharp motion.
