Uninterested

Uninterested

Adjective · /ʌnˈɪntrəstɪd/ · having no interest in something; not curious or concerned

Definition

Uninterested means having no interest, curiosity, or concern about something. It describes a state of genuine indifference — you simply do not care, you are not drawn in, you feel no pull toward the subject. The teacher spoke for an hour while half the class sat uninterested. It is different from disinterested, which means impartial or without personal stake — a common and important confusion. Uninterested = not interested. Disinterested = not biased.

Origin

Uninterested is formed from the negative prefix un- and interested, which derives from the Latin interesse — to be between, to matter, to concern. By the eighteenth century, interested had split into two distinct senses: having a personal stake, and having curiosity or attention. Uninterested took the second sense: lacking attention or curiosity. The confusion with disinterested grew in the twentieth century as disinterested began to be used colloquially to mean simply bored or indifferent, which purists still resist.
