Synonym discussion
Sense: verb/1
When someone communicates back to us, 'reply' is the most direct way to describe providing an answer. 'Respond' is more formal and versatile, covering both verbal replies and physical actions, such as how a body might respond to a sudden cold draft. 'Acknowledge' is more specific than the others, implying that we have received a message but not necessarily providing a full answer to its content.

Etymology
The word comes from the Latin 'respondere,' which means to 'promise in return.' The prefix 're-' means 'again' or 'back,' and 'spondere' means to 'pledge' or 'promise.' Originally, it carried the idea of fulfilling an obligation by giving an answer, which later evolved into our current general use of replying or reacting.
