What does curly mean?
Curly is an adjective describing something that forms or is covered in curls — tight spirals, ringlets, or winding curves. Its dominant use by far is for hair: someone with curly hair has locks that twist naturally into ringlets rather than hanging straight. The word extends comfortably beyond hair to any object or line marked by looping curvature, as in curly handwriting, the decorative curly flourishes of old manuscripts, or the 'curly brackets' — { } — used in mathematics and programming. Derived directly from the noun and verb curl, it also yields rarer derivatives such as curliness. Curly sits at a neutral-to-warm register: it is descriptive rather than evaluative, though in some cultural contexts curly hair has been celebrated as a distinctive feature. Simple, vivid, and instantly visual, it is among the most common everyday descriptors of appearance in English.
adjectiveHaving curls or a winding, spiralling shape; covered with or forming tight curves.
- Of hair or fur: growing in or arranged into curls rather than hanging straight.
- Shaped in or marked by curls, coils, or winding curves more generally.
"She pushed her curly hair behind her ears before starting the exam."
"His curly hair sprang back into place the moment he let go of it."
"The handwriting trailed across the page in long, curly flourishes."
In typography and programming, the { } symbols are affectionately called 'curly brackets' — one of the rare cases where this playful adjective names a piece of technical infrastructure.

Etymology of curly
Curly is formed simply from curl, adding the common adjective-forming suffix -y. Curl itself appeared in English in the fifteenth century, but its deeper origins remain genuinely uncertain; it has been linked to Middle Dutch or Middle Low German forms such as krul, though scholars have proposed other sources and no derivation is firmly established. Because curl's ancestry is obscure, there are no confidently identifiable cognates sharing its root, and the word's history is best described as native English usage built on a borrowing of unclear provenance.
