覚え方のコツ Memory Tip
aggressive を知っていれば、aggressiveness は「攻撃的である性質・傾向」と取りやすい。-ness は kind→kindness と同じで、形容詞を「性質・状態」の名詞にする形。aggression が一回の攻撃行為そのものを指しやすいのに対し、aggressiveness はその人や態度に備わった攻撃性を表しやすい。show aggressiveness, excessive aggressiveness のようなかたまりで覚えると、単なる energy や assertiveness と混同しにくい。
If you know aggressive, this is the quality form with -ness, like kind to kindness. Aggression often points to an act, but aggressiveness is more about a person's usual attitude or style. Remember phrases like "show aggressiveness" or "excessive aggressiveness" so you do not confuse it with simple energy or confidence.
例文
The dog's aggressiveness towards strangers is concerning.
その犬の見知らぬ人への攻撃性は懸念される。

aggressiveness の語源・成り立ち Etymology
aggressiveness は aggressive に -ness が付いた語で、aggressive はラテン語 aggredi に由来します。ad-「〜へ」+ gradi「歩む」で、本来は「相手へ踏み出す」ことから「攻撃的」が生まれました。progress や digress も同系です。
Aggressiveness comes from aggressive plus the noun ending -ness. Aggressive goes back to Latin aggredi, made from ad- "toward" and gradi "to step." The original image was stepping toward someone, which later developed into the sense of attacking or pushing forward strongly. Related English words from the same root include progress and digress.
