bradywang 寫:"I had a big tongue bite"
If you really want to mention "洞", you can say
"I had a big tongue bite and found one bump there"
"have/take a bite" means you eat something.
"bite" can mean a small hole made where an animal or insect has bitten you
sentence: The infection is passed by the bite of a mosquito.
snake, ant...... bites
(Longman dictionary of contemporary English Online)
So I feel "I had a big tongue bite" is weird.
How about I bit my own tongue and there is a big painful sore there?
