Origin:
Counterblast , predictably, comes from the roots "counter" and "blast." It came into common English usage in the 1560s. The prefix counter- originates in the Latin word contrā which meant "against, to return." Blast , on the other hand, originates in Old English, from the word blǽst , which meant "to blow."
