IPA: /ˈtiːzələr/
KK: /ˈtiːzələr/
A person who uses teasels, which are plants with prickly heads, to create a raised texture on fabric.
The teaseler skillfully prepared the cloth to give it a soft, fuzzy finish.
The word 'teaseler' originates from Old English 'tǣse' (meaning to tease or provoke) combined with the agent suffix '-er' (meaning a person who). A teaseler is a person who teases or provokes others.
Think of someone who 'provokes' ('tǣse') others — that's what a teaseler does, as the '-er' indicates a person.
