What does bellying mean?
Bellying is the present participle of the verb 'to belly', which describes something swelling or bulging outward in a rounded shape — most classically a sail filling with wind. The word belongs chiefly to nautical and descriptive prose, where phrases like 'bellying sails' or 'canvas bellying in the breeze' convey both motion and force. Beyond sailing, it can describe tents, shirts, curtains, or any flexible material that puffs out under pressure from air or water. The image it evokes is visceral and physical, drawing on the familiar roundness of the human belly, from which the verb derives. Bellying carries no strong connotation of its own; its effect comes from context, suggesting fullness, strain, or the push of an unseen current. It should not be confused with bellowing, the roaring cry of a bull or an angry shout, despite their near-identical spelling. For writers seeking a vivid alternative to 'bulging' or 'billowing', bellying offers a precise and evocative choice.
To swell or bulge outward like a belly, especially said of a sail filled with wind.
"The jib was bellying as the boat ran before the wind."
Most common in nautical contexts.
In nautical use, the bulging central part of a sail when full of wind.
"Trim the sheet until the bellying of the sail is even."
Specialist nautical usage.
Rare; the plural is used only in technical descriptions of repeated instances of sail bulge.
"The crew adjusted for the varying bellyings of the headsails."
A single letter separates bellying from bellowing — one word fills a sail with wind, the other fills a stadium with noise.

Etymology of bellying
Bellying derives from 'belly', an Old English word (bælg/belg, related to Old Norse belgr) originally meaning a bag or skin, which came to denote the abdomen and then anything resembling it in roundness. The verb 'to belly' — to swell out like a belly — developed from this noun sense and has been used of sails since at least the early modern period. Its cognates include Germanic relatives such as German Balg ('skin, bag') and Old Norse belgr, reflecting the word's ancient association with containers and pouches.
