What does bellyache mean?
Bellyache serves two related but distinct purposes in modern English. In its original and most literal sense, it is a noun meaning a pain in the stomach or abdomen, used informally in both British and American speech alongside terms like stomachache. More colorfully, bellyache also functions as a verb meaning to complain persistently and pettily — to grumble, whine, or gripe about things that others consider trivial. This figurative sense, common especially in North America, gives the word a mildly dismissive edge: telling someone to stop bellyaching implies their complaints are more noise than substance. The word is transparently compound, combining 'belly' with 'ache,' which makes its literal meaning instantly clear even to new learners. Its dual identity — physical discomfort on the one hand, verbal grumbling on the other — makes it a compact and expressive addition to everyday vocabulary.
A pain in the stomach or abdomen.
"All that fairground food gave him a nasty bellyache."
Informal; more conversational than 'abdominal pain' or 'stomachache.'
To complain persistently and grumblingly, especially about trivial matters.
"She was bellyaching all morning about having to work the weekend."
Chiefly North American; strongly informal and slightly dismissive.
The plural applies to the noun sense (instances of abdominal pain); the verb does not take a plural.
"Recurring bellyaches sent her to the doctor for tests."
Bellyache does double duty: it's both the ache in your gut and the complaint coming out of your mouth — English decided one word could cover both.

Etymology of bellyache
Bellyache is formed by straightforward compounding of 'belly' (from Old English 'bælig') and 'ache' (from Old English 'acan'), making it a genuinely Germanic English word rather than a Latin or French borrowing. The literal sense of abdominal pain has been in use for centuries. By the nineteenth century, particularly in American English, the word developed a figurative verb sense meaning to complain grumblingly, extending the idea of internal discomfort to outward grumbling.
