What does stomachache mean?
A stomachache is an ache or pain in the stomach or upper abdomen, often caused by indigestion, overeating, food poisoning, or a stomach illness. In everyday use, it can also describe general digestive discomfort, sometimes accompanied by nausea. The term is informal and familiar, and it is especially common in speech and health-related advice. British English generally favors the closed compound “stomachache,” while American English often uses the two-word form “stomach ache.” Unlike a medical term such as “abdominal pain,” a stomachache is a lay expression: it identifies the area of discomfort without establishing a precise diagnosis. Although the condition can be minor and temporary, persistent or severe pain may require medical attention. The word is useful because it captures a common, ordinary experience in accessible language.
Pain or an uncomfortable sensation in the stomach or abdomen.
"He complained of a severe stomachache."
Common and informal; often used for indigestion or other minor digestive discomfort.
To suffer from a stomachache.
"The child stomachached all afternoon."
Less common and more informal than the noun; especially associated with American English.
The plural is formed by adding -es to the headword.

Stomachache is a compound built from two everyday words: the body part that hurts and the old word for a painful sensation.

Where does stomachache come from?
“Stomachache” is a compound formed from “stomach” and “ache.” “Stomach” entered Middle English from Old French estomac, ultimately from Greek stomachos, meaning the mouth or stomach, while “ache” comes from Old English æce and is related to other Germanic words meaning pain. The compound has been used in English since at least the early 17th century, and its spelling has varied between the open and closed forms over time.
