The word 'talker' is a transparent English compound built from the native Germanic verb 'talk' and the agentive suffix '-er'. The verb 'talk' itself emerged in Middle English, likely as a frequentative form related to 'tell' or 'tale', emphasizing the act of speaking or narrating. The suffix '-er' has deep roots in Proto-Germanic -ārijaz, borrowed into Latin as -arius but functioning natively in English to denote "one who does" something. Therefore, a 'talker' literally means "one who talks," a logical and direct construction that has retained its core meaning from its Middle English origins to modern usage.
