I thought I knew what romance meant, so hadn't previously looked it up. According to my dictionary it's a feeling of excitement and mystery, most usually associated with love. Does that surprise you? It did me a little – not the excitement part so much as the mystery element, and it's not that these form part of the definition, but that they're all of it.
I've always thought of romance as being at least partly 'nice', pink and fluffy, sugar sweet. Maybe I've been romanticising the word? To romanticise (or romanticize) is to deal with, look at, or describe things in an idealised fashion or make them seem better or more appealing than they really are.
Romance can also mean feelings of excitement, mystery and remoteness associated with other things, such as the romance of travel, the wild or the sea.
If a person is romanced then they'll be the subject of actions intended to gain their love. If you're the one doing this then you're romancing the other party – good luck with that!
My latest collection Lots Of Love contains 25 short stories all connected in some way with love or romance.
