I need a more formal word or phrase for saying "beat up." My sentance is something like 'he beat him up' but i`m writing a formal piece so I need to substitute the phrase for something more formal. Any ideas?

Attacked, assaulted, mugged, etc.

:O thanks

Certainly! In more formal writing, you can replace the phrase "beat up" with the following alternatives:

1. Assaulted: For example, "He assaulted him."
2. Attacked: For example, "He attacked him."
3. Pummeled: For example, "He pummeled him." (Note: This carries a connotation of heavy, repeated blows.)
4. Thrashed: For example, "He thrashed him." (Note: This conveys a sense of forceful and violent physicality.)
5. Struck: For example, "He struck him." (Note: "Struck" is a more general term that could refer to a single blow or a series of blows.)

Remember, regardless of the word choice, it's essential to use language appropriate for the context of your formal piece.
