What does comprize mean?
"Comprize" is an obsolete variant spelling of the verb "comprise," meaning to consist of or be made up of particular parts, or more broadly to include or encompass something within one's scope. In older English texts — legal deeds, contracts, histories, and literature from the seventeenth through nineteenth centuries — a writer might say that an estate comprized several hundred acres, or that a nation's territory comprized distant islands. The word carries no meaning distinct from "comprise"; it is purely a spelling difference reflecting the era before orthography was standardized, when the final -ize ending was commonly written -ize rather than -ise regardless of etymology. Today, "comprize" appears only in archival sources and scholarly editions, and readers encountering it should mentally substitute "comprise." Because "comprise" itself is frequently confused with "compose," the distinction matters: a whole comprises its parts, while the parts compose the whole. Knowing "comprize" is less about using it than about recognizing it accurately in historical documents.
verb"Comprize" is an archaic spelling variant of the verb "comprise," meaning to consist of or be made up of specified parts, or to include within a larger whole.
- To consist of or be made up of specified elements or parts (of a whole with respect to its parts).
- To include, encompass, or contain within its scope.
"The estate comprized several hundred acres of woodland and pasture, as the deed recorded it in 1789."
"The kingdom's dominions comprized not only the mainland but also several distant island territories."
"As written in the original contract, the purchase comprized all fixtures, furniture, and livestock on the property."
If you find "comprize" in an old book, don't assume it's a typo — before standardized spelling took hold, this was simply how many writers spelled "comprise."

Etymology of comprize
"Comprize" shares its origin entirely with "comprise": both derive from the French "comprendre," from Latin "comprehendere," meaning to grasp or take in together, formed from "com-" (together) and "prehendere" (to seize). The variant spelling arose because English writers did not consistently mark whether such verbs came from French -dre endings, so forms in -ise and -ize coexisted for centuries. The same Latin root also produced "comprehend" and, via related paths, words like "enterprise" and "apprehend." As spelling conventions hardened in the nineteenth century, "comprise" became the accepted form and "comprize" fell out of use.
How comprize is actually used
"Comprize" is obsolete in modern usage; contemporary writing should use "comprise" instead. It survives mainly in historical documents, legal texts, and literature from earlier centuries. Like "comprise," it was sometimes misused in the pattern "is comprized of," which careful writers avoided even historically.
