Acknowledge

Acknowledgments are utterances consisting of short phrases such as “ok”, “yes”, “uh-huh”, that signal that the previous utterance was understood without necessarily signaling acceptance. They do not resolve the content of the utterance they address. ”right”, ”alright” and ”ok” are ambiguous. They are commonly only an acknowledge when they are followed by a hint. ”OK” is commonly used after a not totally wrong answer.
