What does armorial mean?
"Armorial" means relating to heraldry — the system of hereditary symbols, most famously coats of arms — used across Europe to identify families, institutions, and individuals. As an adjective, it describes anything connected with armorial bearings: armorial banners, armorial porcelain, armorial bookplates, or armorial stained glass commemorating a patron or benefactor. Less commonly, "armorial" functions as a noun denoting a book or roll that records the arms of many families, and surviving medieval armorials are prized sources for genealogists and historians tracing noble lineages. The word derives ultimately from Latin arma, "arms," via Old French, placing it in the same family as "armor" and "armory." Because it belongs to the specialized vocabulary of heraldry, it carries a scholarly, antiquarian tone and appears mostly in formal writing about history, art, and genealogy rather than in casual conversation. For anyone researching family crests or historic buildings, however, it is an indispensable term.
Of or relating to heraldry or coats of arms.
"The library commissioned an armorial binding stamped with the founder's crest."
Almost always used attributively before a noun, as in "armorial bearings."
A book or manuscript containing a collection of coats of arms.
"A richly illuminated armorial from the 1400s sold at auction for a record price."
Used mainly by historians, archivists, and collectors; often qualified by date or origin, e.g. "a Flemish armorial."
The plural applies only to the noun sense (books or rolls of arms); the adjective has no plural form.
"Medieval armorials survive in libraries across Europe, preserving the arms of long-extinct families."
Every coat of arms on a medieval stained-glass window owes its place to someone compiling an 'armorial' — the heraldic equivalent of a phone book for noble families.

Etymology of armorial
Armorial comes from the Old French "armoirie" or "armoire," meaning a coat of arms, which itself descends from Latin "arma," meaning weapons or arms. The adjective entered English in the late Middle English or early modern period alongside the vocabulary of heraldry. It shares its root with "armor," "armory," and "armament," all stemming from the same Latin source.
How armorial is actually used
Armorial is a formal, specialist term found mainly in heraldic, genealogical, antiquarian, and art-historical writing. The adjectival use is far more common than the noun; in everyday speech it rarely appears outside discussions of family crests, stained glass, manuscripts, or official insignia.
Easily confused with armorial
An armory is a place where weapons are stored (or a collection of such knowledge), while armorial describes things relating to heraldic coats of arms.
