What does jagg mean?
Jagg is an uncommon English word with two related but distinct uses. As a noun, it denotes a sharp projection, point, tooth, or notch, particularly a feature of a cogwheel, saw, or other mechanical object. As a verb, it means to move or act with sudden jerks. The word is chiefly associated with archaic, dialectal, and Scottish usage and is much less common than jag, its more familiar modern relative. Its mechanical sense gives it a precise, practical quality: the damaged projection on a wheel could be described as a jagg, and the irregular motion produced by such a defect might be described as jagging. Although the term survives in older writing and regional speech, it is now most often encountered in dictionaries, historical texts, or literature seeking a deliberately old-fashioned sound. It should not be confused with jag, the common modern form, or with jaggery, the unrefined cane sugar.
A sharp point or projecting edge, especially a tooth or notch in a wheel, saw, or similar object.
"The mechanic replaced the broken jagg in the gear wheel."
Chiefly archaic or dialectal; still used in some Scottish and northern English speech.
To move or act with sudden jerks; to jerk or jolt.
"The cart jagg ed over the uneven track."
Rare and chiefly dialectal or archaic.
The standard plural is jaggs, although it is rarely encountered because the noun itself is uncommon.
"Several worn jaggs were visible along the rim of the wheel."
Jagg is essentially the old name for the sharp tooth or point that gave us the familiar words jag and jagged.

Where does jagg come from?
The Middle English forms jagge and jag came from Old Norse jag, a word for a projecting point or tooth, ultimately traced to a Germanic root. Jagg continued this word in an older English spelling, while the related adjective jagged was formed within English from the same jag stem. The verb meaning 'to jerk or jolt' belongs to the same lexical family.
