“There's a bug buzzing around my head!”
You're hiking in the woods. A fly keeps flying around your head while making a noise. Annoyed, you say this.
There's a bug buzzing around my head!
Use "there's ___" when you're describing a situation that's happening now:
There's someone at the door.
There's some food in the kitchen, if you're hungry.
Or something that's planned for the near future:
There's a game coming on at four.
It's also common to describe what something is doing using "there's":
There's a woman staring at you over there.
There's a humming noise coming from the refrigerator.
There's some cake sitting on the counter.
A "bug" is an insect, like a fly, mosquito, ant, grasshopper, etc.
What kind of bug is that?
I don't like the country. Too many bugs.
The word "insect" is more formal and a little more scientific-sounding than "bug".
"Buzz" is a word that describes a sound. "Buzzing" is a kind of medium- to high-pitched noise that is made by:
- a broken fan
- a cell phone that's ringing while in silent mode
- a far-away helicopter
In addition to describing a sound, "buzz" can also describe the action of an insect flying around while making a buzzing noise.
