覚え方のコツ Memory Tip
clocking は原形 clock「時間を計る・記録する」に -ing を付けた現在分詞・動名詞です。clock はすでに -ck で終わるため文字を追加で重ねず clocking、発音は /ˈklɑːkɪŋ/ など。コーチが clocking each runner や every lap と、時計でタイムを記録する場面で覚えましょう。
Connect clocking directly with a clock or stopwatch being used to measure performance. The base verb is clock, and its -ing form is clocking; because clock already ends in ck, no extra consonant is added. Pronunciation varies with the accent, such as /ˈklɑːkɪŋ/ in much American English. Picture a coach clocking each runner and writing down every lap time. This keeps the intended sense focused on measuring or recording elapsed time, rather than unrelated informal meanings of clock such as hitting someone or noticing something.

彼らは先週、配達時間の計測を始めました。
Clocking every lap helped the team see where the runner slowed down.
各周のタイムを計測することで、チームは走者がどこで減速したかを把握できました。

clocking の語源・成り立ち Etymology
中英語やオランダ語の「clocke」（鐘）に由来し、語根は鐘を意味する「clock」に動作の「-ing」を加えます。時刻を知らせる鐘が時間計測装置そのものを指すよう転じ、時間を測る意味へ発展しました。同語根の例に「clockwise」があり、鐘の合図から時間管理へ繋がる過程が納得できます。
Clocking is made from the verb clock plus the participial suffix -ing. Clock entered Middle English through forms related to Middle Dutch clocke and Old North French cloque, originally meaning “bell.” Bells announced the hours, so the word came to denote a device that displays or measures time. English then developed the verb clock, meaning to time or record a duration or speed, from which clocking follows regularly.
