Aphotic is an adjective that means ‘having no light.’
Our word of the day combines the Greek prefix ‘A,’ meaning ‘without’ with ‘photic’ (FOE tick) meaning ‘light.’ Frequently used in nature, aphotic describes a thing or place that has no light.
We were hoping to get some great pictures on our underwater dive. But unfortunately, the aphotic conditions simply made it too dark for that to happen.
