niche noun [ C ] (POSITION) âº a job or position that is very suitable for someone, especially one that they like: He has carved/made a niche for himself as a financial advisor. âº an area or position that is exactly suitable for a small group of the same type: an ecological niche.
A niche is a space that's all your own, from a literal corner or enclosure to some kind of professional specialty. Like finding a niche in the scented soaps market with peanut butter body wash and winning over a loyal, if not nutty, following. In the 1600s, niche was first recorded as meaning a âshallow recess in a wall.. The figurative sense of the word didnât come about for another century. So today, you can use niche literally to refer to a cranny or crevice, or figuratively to talk about an activity or role in life that is particularly suited a personâs interests or talents.
