hmph; pish; pooh
A dismissive or scornful snort, expressing contempt, disbelief, or a feeling of superiority. Often used when looking down on someone or something.
A light, sometimes self-satisfied acknowledgment, similar to 'oh, I see' or 'ah, indeed'. Can carry a nuance of smugness or knowingness.
Oh, I see. That makes sense.
"Hmph, that's easy," he said with a snort.
