'Angreifen' (to attack) is a separable verb. The prefix 'an-' comes at the end in a main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Der Feind greift die Stadt an.
The enemy attacks the city.
The verb consists of the prefix 'an-' and the verb 'greifen' (to grab). The literal meaning is therefore 'to reach for something in order to grasp it,' which describes the idea of an attack well.
Der Löwe greift seine Beute an.
The lion attacks its prey.
The object of the verb helps you understand the meaning. A country or a person is attacked militarily or verbally. A material or health is attacked by something, such as acid or stress, meaning damaged.
Der Politiker griff seinen Gegner verbal an.
The politician verbally attacked his opponent.
When 'angreifen' (to attack) describes a verbal attack, it is often combined with adverbs such as 'scharf' (sharply), 'persönlich' (personally), 'direkt' (directly), or 'öffentlich' (publicly).
Der Journalist hat den Minister in seinem Artikel scharf angegriffen.
The journalist sharply attacked the minister in his article.
In the meaning 'schädigen' (to damage), the subjects are often abstract things like stress, an illness, or chemicals. The objects are then often health, the immune system, or materials.
Der viele Stress greift seine Gesundheit an.
All the stress is damaging his health.
to criticize
'kritisieren' and 'angreifen' can both mean that someone speaks against a person, an idea, or a behavior. 'kritisieren' is the more neutral word: you point out mistakes or problems, and you can remain factual while doing so. 'angreifen' sounds stronger and harsher. It means a sharp, often personal verbal attack. Learners may confuse the words because both can be negative. If you are calmly talking about shortcomings, 'kritisieren' fits better. If the words are very direct, aggressive, or hurtful, 'angreifen' is more precise.

Nach der Nachricht griff der Politiker seinen Gegner in der Presse scharf an.
After the news, the politician sharply attacked his opponent in the press.
Ich kritisiere den Plan, weil wichtige Kosten fehlen.
I am criticizing the plan because important costs are missing.
