覚え方のコツ Memory Tip
practicing は動詞 practice に -ing を付けた現在分詞・動名詞で、語末の無音の e を落として practice → practicing とします。発音は /ˈpræk.tɪ.sɪŋ/。practice the piano や practice speaking English のように、上達のため反復している場面と結び付けましょう。
Start with the verb practice, meaning to repeat an activity in order to improve. To add -ing, remove the final silent e: practice becomes practicing, pronounced /ˈpræk.tɪ.sɪŋ/. Link the form to an activity visibly in progress: She is practicing the piano. As a gerund, it names the repeated activity itself, as in Practicing every day helps. Remember common patterns such as practice a sport, practice the piano, and practice speaking English. Unlike merely doing something once, practicing emphasizes repetition directed toward better skill or performance.
例文

He spends an hour practicing basketball every morning.

practicing の語源・成り立ち Etymology
ギリシャ語prattein（行う・実行する）からpraktikos（実践的な）が生まれ、中世ラテン語practicareを経て英語practiceとなった。「理論でなく実際にやる」が核心。関連語：practical（実用的な）、praxis（実践）。繰り返し行う意味が定着した。
Practice ultimately traces back to Greek words associated with doing and action, including praktikos, “fit for action” or “practical.” It entered English through Latin and French forms. The central historical idea is action or application rather than theory, which explains both the sense of carrying out a profession and the modern sense of repeatedly performing a skill. Practicing is the English -ing form of the verb practice.
