Definition
化脓 is a separable verb (离合词) meaning 'to fester, to suppurate' — used for wounds or infections that produce pus. The verb 化 and the object 脓 can split: you can insert a measure word or duration between them (e.g., 化了一次脓 'festered once'), or add a result complement after 化 (e.g., 化出脓来 'pus came out'). This word is formal and mostly medical.
