Word Origin
The derivation of the word iridescent is partly from the Greek word  îris (ἶρις) meaning ‘rainbow’, combined with the Latin suffix -escent, meaning ‘having a tendency toward’. The word iris in turn derives from the Greek goddess Iris, a messenger of the gods, who is the personification of the rainbow.

Use in a Sentence
1) The damselfly’s iridescent body shimmered as it flitted with deadly intent beside the stream.

This is the first time I’ve actually managed to use one of my own pictures on a WOW post! As soon as I decided to do the word iridescent this week I just knew I’d have to include one of my damselfly pictures. I hope you like it – and the rest of the post as well, of course!

    1. Thank you. I’m glad you like it! And whenever you get to it is fine. 🙂 It sometimes takes me quite a while to get through everything I want to read on wordpress – I have so many things on the go that fitting everything in is tricky. 🙂
