To Attack
To Assault, To Assail
transitive verb, ichidan verb
You don't say "to aggression." When you do aggression on someone, you're probably doing something to hurt them in some way. This is an attack, making this word to attack. This refers to a planned attack, though. Think about what you're going to do. Plan it out. Then, 攻める!
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
To attack someone, use a celery (せ) stick. Celery is not a deadly weapon but most people hate it, so it's perfect to casually attack someone, especially those who hate celery.
理屈は抜きにして、とりあえず攻めて攻めて攻めまくりました。
Setting all logic aside, I just attacked and attacked and attacked.
