What does uncurl mean?
Uncurl is a transitive and intransitive verb meaning to undo a curl or coil. A person can uncurl a ribbon, a fern frond, or a tightly rolled sheet, and an object may uncurl by itself when tension is released. The word also has a figurative use, especially for relaxing after being tense or restrained: “Uncurl your fingers and rest,” for example, refers both to physically opening the hands and, metaphorically, to letting tension go. Its meaning is therefore broader than simply reversing a mechanical twist. “Uncoil” is a close alternative when the emphasis is on unwinding a mechanically wound object, while “unfurl” often suggests opening out and spreading, especially fabric, flags, or folded wings. Uncurl is ordinary in descriptions of hair, leaves, paper, tentacles, and ribbons, and can sound more vivid than the flatter “straighten.” It is standard in British and American English and is especially useful when the original shape was curved rather than simply folded or wound.

Where does uncurl come from?
Uncurl was formed in early 17th-century English by adding the reversive prefix un- to curl. Curl entered Middle English from Old Norse kurl, a Germanic word associated with a Proto-Indo-European root meaning “to bend” or “curve.” Uncurl therefore literally means “undo a curl” and follows the ordinary English pattern of prefixed verbs that reverse an action.
