is it realtime?
What is it:
- Real time
- Realtime
- Real-time
- realtime
- real time
- real-time
Someone please clarify, which realtime is the correct one? I am wasting our natural resources by monitoring all of the different ways someone can spell real time. According to the article “The environmental impact of Google searches” “performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle or about 7g of CO2 per search”.
Help me save the planet.

As per Bill Mahr, it’s 2 words, “real time.” However, when it’s used as an adjective “real-time captioning,” it’s hyphenated.
And stop killing the planet.
That is all.

The staid M-W says hyphenate or separate:
