A picky person is someone who is very particular and choosy about what they like or accept. They are often difficult to please and have very high standards. The term 'MINER' is a five-letter word that can be used to describe a picky person. A MINER is someone who extracts valuable minerals from the earth, such as coal, gold, and diamonds. This term is used to describe a picky person because they are very selective in what they choose or accept, much like a MINER carefully selects the most valuable minerals from the earth.
