What does engrailed mean?
Engrailed is a technical adjective used chiefly in heraldry to describe a line of partition or an ordinary — such as a fess, bend, or cross — whose edge is cut into a repeating series of small concave indentations, giving a scalloped appearance. In blazonry the term follows the charge it modifies, as in 'a bend engrailed'. The word derives from the French engrêlé, related to the idea of a fine-toothed or notched edge. Beyond heraldry, 'the engrailed' is also the common name of a grey geometrid moth found across Britain and Europe, named for the wavy, scalloped markings along its wings. Because it belongs almost entirely to specialist vocabularies, engrailed carries a distinctly formal, antiquarian flavour; readers will meet it in armorial descriptions, genealogy, museum guides, and butterfly-and-moth literature rather than everyday speech.
(Heraldry) Having an edge marked by a series of concave, inward-curving indentations like small scallops.
"The banner showed a white cross engrailed upon a black field."
In correct blazon, engrailed follows the noun it qualifies.
A common European geometrid moth (Ectropis crepuscularia), greyish with wavy scalloped lines across its wings.
"We spotted an engrailed resting on the fence post at dusk."
As a noun referring to the moth, the standard plural adds -s. The adjectival sense does not take a plural form.
"Several engravails were drawn to the light trap that night."
In heraldry, flipping the direction of the scallops changes everything: 'engrailed' edges curve in, and its mirror-image rival 'invected' curves out — one tiny arc, two completely different charges.

Etymology of engrailed
Engrailed comes through Middle English from Old French engrêlé, meaning 'notched' or 'fine-toothed', ultimately connected to the notion of small points or teeth. It entered English in medieval times as part of the technical language of heraldry, where precise vocabulary was needed to describe every variation of a shield's edges. Its closest relatives are the verb engrail and the noun engrailment, which denote the same scalloped treatment.

How engrailed is actually used
Almost entirely confined to heraldic description and to entomological contexts as the proper name of a moth species. In blazon it always follows the noun it modifies (e.g. 'fess engrailed'). Rarely encountered outside these specialist registers.
Easily confused with engrailed
Invected describes an edge with outward-bulging convex curves, whereas engrailed has inward-cutting concave indentations — they are mirror images in heraldry.
Engraved means cut into a surface for decoration generally, while engrailed specifically denotes a heraldic edge pattern of concave arcs.
