Word
iridescent

Adverb – iridescently

Pronunciation
ir-i-des-cent (ĭr′ĭ-dĕs′ənt)

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.

2) Gleaming iridescently as the morning sunlight fell upon its surface, the abalone shell fascinated Martha’s grandchildren as it had their parents so many years earlier.

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!
