What does replier mean?
A replier is a person who sends an answer, response, or reply to a question, message, or other communication. The word identifies the person rather than the response itself: the message is the reply, while its author is the replier. It is especially useful in professional, legal, technical, and correspondence contexts, where it may appear in language about deadlines, prompt responses, and obligations to answer. In ordinary conversation, responder is often more natural, while replier can sound somewhat formal or specialized. Although the word is fully established, it is less frequent than either reply or respond. Its ending -er forms an ordinary English agent noun, a productive pattern also found in words such as writer, sender, and provider.

"The replier assured the customer that the problem would be investigated."

The plural is used when referring to multiple people who send replies or responses.
"The two repliers exchanged several messages before reaching an agreement."
A replier is someone who answers—but, unlike a reply, a replier is the person who sends it.

Where does replier come from?
Replier was formed in English by adding the noun-forming suffix -er to reply. Reply ultimately comes through Old French replier from Latin replicare, a verb meaning to unfold and, by extension, to answer or respond. The same Latin root produced English cognates including replicate, replica, and replication.
How replier is actually used
Replier is formal and comparatively uncommon in everyday conversation, where responder or reply may sound more natural. It is often used in technical, professional, or legal contexts when emphasizing the act of responding.
