I want to express the following: "Inhale using your mouth with force or power". It does not sound good to me. Is there any single word or a good phrase to express this?
There are a few words that come to mind, but all have subtle connotations:
- gasp - connotes desperation or exhaustion, the boy gave a gasp of agony.
- gulp - connotes taking in a large quantity of air in a single action, some may gulp air at the water surface but not absorb the contained O2 for respiration.
- suck - connotes drawing in air gradually, he began to suck in air through his mouth.
If I understand what you mean, this is generally described as a sharp intake of breath.
Gasp would be most apt, I reckon.
I think "suck" is the single word that most effectively and consistently implies the meaning you're looking for. "Gulp" to me suggests swallowing, and not with tremendous force. And although "gasp" is close, your intended meaning seems to imply some intention to make the action very powerful; "suck" accomplishes this, whereas "gasp" is typically used for describing a surprised or shocked reaction, which is slightly different, especially given that it is usually involuntary.
But let me add this: In colloquial speech, two more options present themselves. Although they do not express exactly what you are looking for they might work well for you if the context is right. You can say "vacuum" ("he vaccumed up the noodles all at once"), and the jargon/slang form of this is "hoover," as in "he hoovered that pizza like there's no tomorrow." Admittedly, these terms usually relate more to eating than to inhaling, but since their explicit meaning is a forceful intake of air, I'm simply putting them out there for your consideration.
