philatelist (fil ATE a list) This is the noun for someone who collects and studies postage stamps, postmarks, and related materials. The word comes from the Greek word meaning “lover of things that are exempt from pay-ment” because a postage stamp indicates prepayment of postage. Though it looks like an adverb, the noun for the collection of stamps is “philately.”
- Billy is quite a dedicated philatelist. He has books of stamps from all around the world and from many different eras.
