Usage

What is a basic definition of attack? Attack means to attempt to inflict harm with physical violence, to attempt to inflict harm with words, or to initiate a military offensive against another. Attack has many other senses as a verb and a noun. Attack means to engage in physical violence against something with the intent to cause physical harm, damage, or death. Attacking doesn’t have to result in harm, however. For example, a person may be attacked by bees but manage to escape before actually getting stung. Someone or something that attacks is an attacker.

• Real-life examples: A lion will attack with its claws and teeth. In the past, soldiers would attack each other with swords, axes, and other weapons. A scared person may attack a lamp thinking it is a burglar.
• Used in a sentence: Ashley relentlessly attacked the piñata with a broom handle.

Attack can also mean to try to harm someone verbally. In this sense, attack means to assault someone with criticism, insults, or harsh comments. The attempted harm would be to a person’s feelings, opinions, or arguments.

• Real-life examples: Politicians are often attacked by political opponents, critics, or even the media. Unfortunately, many people are often attacked by trolls and harassers on social media. Bad or unpopular ideas are often attacked for being impossible or foolish.

Attack is also used in both senses as a noun.

Attack can also mean to initiate acts of war or begin a military offensive. This sense can also be used as a noun.

Etymology

Origin of attack

First recorded in 1590–1600; earlier atta(c)que, from Middle French atta(c)quer, from Italian attaccare “to attack”; cf. attach

---

Explanation

When you attack, you charge or advance violently. It's scary to watch a big dog attack a smaller dog. In the military, an attack is an advance of troops or the use of armed force against an enemy. When one little kid attacks another, there usually aren't any bombs or weapons involved, but the idea of force or hostility is the same. You might also attack an opponent in a game, or withstand a verbal attack from a classmate during a debate. The Italian source of attack is attacco, "an attack," from attaccare, "join battle."
