His unemphatic response made it clear that he was not very interested in the topic.
Unemphatic → It is formed from "un-" (meaning not) and "emphatic" (from Greek "emphatikos", meaning to show or express strongly). The word "unemphatic" means not expressing something strongly or without emphasis.
Think of 'not' ('un-') showing something 'strongly' ('emphatic') — that's why unemphatic means lacking strong expression.
