Which is/are correct?

1 Answer 1


Wikipedia seems to suggest the third option is correct, near real-time.

While hyphenation is often arbitrary, I would suggest to follow the established usage in this case.

Having said that, in the same paragraph it also uses near-real-time:

...a near-real-time display depicts...

Here near real-time is used as a modifier of display, so the hyphenation clarifies that it is one unit, rather than, say, a near-real time display

  • That difference would be because the "near real-time" case is correct where it is used as a noun phrase, which is what the question was asking about. If you use it as a compound adjective, however, as in "a near-real-time display", then it's a triple-hyphenated-word. Er, I mean, a triple-hyphenated word. Commented Sep 4, 2020 at 5:34
