Hmm vs. Umm: What's the Difference?
By Aimie Carlson & Janet White || Updated on May 20, 2024
"Hmm" expresses thoughtfulness or hesitation, while "Umm" indicates uncertainty or searching for words during speech.
Key Differences
"Hmm" is often used to signal that someone is thinking or considering something. It's a sound that conveys a moment of contemplation or pondering over a matter. "Umm," on the other hand, is commonly used as a filler word during speech, indicating uncertainty or hesitation. It often appears when someone is searching for the right words to say or trying to gather their thoughts.
In conversation, "Hmm" is typically followed by a statement or decision, whereas "Umm" often precedes a pause or a question. "Hmm" can indicate deeper thinking or consideration, suggesting the person is processing information internally.
"Umm" is more spontaneous and less reflective, usually emerging in the flow of speech as a way to fill silence and avoid abrupt pauses. It helps to keep the conversation going smoothly even when the speaker is momentarily unsure.
While "Hmm" can sometimes be drawn out to emphasize contemplation, "Umm" is generally shorter and more frequent, highlighting immediate uncertainty. Both sounds play distinct roles in verbal communication, aiding in the expression of thought and hesitation.
