Describing someone or something that does not have a partner.
After the dance, she felt partnerless and a bit lonely.
Partnerless → It is formed from "partner" (from Old French *parcener*, meaning to share or divide) and "-less" (meaning without). The word "partnerless" means without a partner or companion.
Think of being 'without' ('-less') a 'partner' — that’s what partnerless means.
