Counter-accuse, which means to accuse someone who has accused you, has several synonyms that can be used in place of it. One option is "retaliate," which suggests a response to an attack or criticism with similar force. Another possibility is "recriminate," which refers to the exchange of accusations or insults between parties. "Rebut" and "refute" are also viable alternatives, indicating an attempt to disprove or deny the accusations made against you. Finally, "denounce" can be used in some contexts, emphasizing a strong public condemnation of an accuser or their accusations. Whichever synonym you choose, it's important to use language that is both accurate and appropriate for the situation at hand.
