What’s the plural of matrix?
The plural of matrix is matrixes or matrices. Matrix comes from Latin, which evidently showed other patterns of noun transformation than the standard –s/-es in Modern English. The -ex/-ix suffix pattern is common across Latin-derived nouns, and commonly these nouns modify to –ces as a pl. n. form. Over time (and frequent confusion on the part of English speakers), –xes, or simply adding the –es most likely came to be accepted (or was introduced by way of American English).
The Latin pattern: matrix (-ix) can be matrices (-ices), like appendix/appendices.
