IPA: /ˈbloʊbɔl/
KK: /ˈbloʊbɔl/
A fluffy seed head of a dandelion that can be blown away by the wind or by people, often enjoyed by children.
The children had fun blowing the blowballs into the air.
The word 'blowball' is formed from 'blow' (from Old English 'blāwan', meaning to emit air) and 'ball' (from Old English 'beall', meaning a round object). The term 'blowball' refers to a round seed head of certain plants, such as dandelions, that can be blown to disperse seeds.
Think of 'blowing' air to send seeds flying from a 'round object' — that's what a blowball is.
