覚え方のコツ Memory Tip
原形 misbehave「不適切に振る舞う」の語末の黙字 e を落として -ing を付けた形で、/ˌmɪsbɪˈheɪvɪŋ/ と発音します。mis- は「悪く・誤って」を示します。ここでは動作の進行より、misbehaving during a test や repeated misbehaving のような「問題行動」という名詞的用法を覚えましょう。
Begin with the verb misbehave, meaning “to behave badly or improperly.” To form misbehaving, drop the silent final e and add -ing; it is pronounced /ˌmɪsbɪˈheɪvɪŋ/. The prefix mis- signals that an action is wrong or unsuitable, while behaving concerns how someone acts. In this entry, treat the whole form as an activity or type of conduct, as in misbehaving during a test or repeated misbehaving in the laboratory. Unlike a single accidental mistake, it often suggests behavior that violates rules or expectations.

misbehaving の語源・成り立ち Etymology
接頭辞 mis-（誤った・悪い、古英語 mis-）＋ behave（振る舞う）の動名詞形。behave はbe- + have（持つ）で「自らを保つ→振る舞う」が原義。misconduct（不品行）、misdeed（悪行）と同様に、mis- が行為の逸脱を示す。
Misbehaving is the -ing form of misbehave, created by dropping the silent final e before adding -ing. Misbehave combines the Germanic prefix mis-, meaning “wrongly” or “badly,” with behave. Behave developed from be- and have and came to refer to conducting oneself in a particular way. As in misconduct and misdeed, mis- marks a departure from acceptable or expected action.
