Etymology: "Tatamis" is simply the plural of "tatami," so the real story belongs to the singular. The word comes from Japanese "tatami," a verb-derived noun from "tatamu," meaning "to fold up" or "to pile up." Early tatami were not floors at all but thick, portable mats that could be folded and stacked when not in use, and they were laid out only where people sat or slept. Over centuries, as they became standard covering for whole rooms, the word followed the material's shape rather than its original function. The plural itself is a later English habit. Japanese does not mark plurals on nouns like this, so "tatamis" is an English addition. Speakers who want to avoid it often write "tatami mats" or simply "tatami" for a group.
