suppositio materialis
a Latin phrase in logic for a word or phrase used without semantic function, and regarded only as the letters or sounds, from suppositio "assumption, hypothesis" (see supposition) + Late Latin materialis (adj.) "of or belonging to matter," from Latin materia "matter, stuff, wood, timber" (see matter (n.)).
"There are no verbs in 'the Bible' " is both true and false, but true only as suppositio materialis.
