IPA: /ˈdæblər/
KK: /ˈdæblər/
A person who tries out different activities or interests without committing to any of them seriously.
He is a dabbler in painting, but he has never taken a class.
Dabbler → The word originates from the Middle English 'dabblen', which means to splash or to wet. It is a frequentative form of 'dab', which means to touch lightly or to make a slight movement. A dabbler is someone who engages in an activity in a superficial or casual manner, as if splashing lightly in it.
Think of someone who 'touches lightly' or 'splashes' in different activities without fully committing — that's what a dabbler does.
