核心畫面
One way to picture it: towards someone in order to attack — the first move, made by you, not a response to being hit.

一個人朝著別人「跨步逼過去」。關鍵不在於有沒有真的打下去，而在於那個方向——是你主動朝對方走過去的，不是被打了才還手。aggression 講的就是這股主動撲上去的勁：可能表現成怒氣、威脅的姿態，也可能表現成真正的動手。From the word’s history
From Latin aggressiō, from aggredior 'I go towards, I approach, I attack' — ad- 'towards' + gradior 'I step, I walk'. The literal picture is of stepping up to someone.
來自拉丁文 aggredior：ad-（朝向）+ gradior（走、跨步），字面就是「朝某人走過去」，進而是「上前攻擊」。gradior 這個字根也留在 grade、gradual、progress 裡，全都跟「步」有關。所以 aggression 骨子裡是一個身體動作的畫面：主動跨出那一步。
Wiktionary — Latin aggressiō, from aggredior (ad- + gradior 'to step').
