What does eruct mean?
To eruct is to belch — that is, to release gas from the stomach through the mouth, often audibly. The word derives from the Latin eructare, built on rumpere, 'to break,' and entered English in the early modern period as a learned alternative to plainer terms like belch or burp. Because of its clinical, Latinate character, eruct today carries a distinctly formal, technical, or wryly humorous tone; it is unlikely to surface in casual conversation except as a deliberate flourish. A rare figurative extension applies the verb to volcanoes and similar sources that violently discharge smoke, ash, or molten rock, though this usage is largely literary. The most common derived form is the noun eructation, which survives chiefly in medical writing. For readers who enjoy precision with a touch of pomposity, eruct offers an elegant — if slightly comic — upgrade to one of the body's least dignified acts.
To belch; to emit gas from the stomach through the mouth.
"The infant eructed loudly after being burped over her mother's shoulder."
(Of a volcano or similar source) To eject or discharge matter forcefully.
"The crater continued to eruct steam long after the main eruption had ceased."
"Eruct" is the delightfully formal way to say "burp" — a word your stomach performs daily but your dictionary rarely gets credit for.

Etymology of eruct
Eruct comes from the Latin eructare, formed from ex- ('out') and ructare ('to belch'), which itself traces back to rumpere, 'to break.' It passed into English in the late sixteenth or early seventeenth century as part of the era's broad borrowing of Latin vocabulary. It shares its deep root with words such as erupt, rupture, disrupt, and abrupt, all of which preserve the underlying idea of breaking or bursting forth.
