IPA: /ˈkɛəfriː/
KK: /ˈkɛrˌfri/
Not having any worries or responsibilities; feeling relaxed and happy.
On her vacation, she felt carefree and enjoyed every moment without stress.
Carefree → It is formed from "care" (from Old English *caru*, meaning worry or concern) and "free" (from Old English *freo*, meaning not in bondage or unrestricted). The word "carefree" describes a state of being without worry or concern, enjoying freedom from anxiety.
Think of being without 'worry' ('care') and feeling 'unrestricted' ('free') — that's what it means to be carefree.
