I would like to know if there is a single-word hypernym for day, month, week and year.

  • Have you checked past questions on ELU? And elsewhere, esp., online?

  • Yes I have checked Dec 24, 2012 at 14:46
  • Er... interval? Duration?

  • Time interval (may be, although it's 2 words), duration - aswers the question how long, I am looking for something that answers the question when Dec 24, 2012 at 14:57
  • But "day", "month", "week" or "year" do not answer the question "When?"

Time period is general enough:

time period n. an amount of time

  • I thought of this one, just wasn't sure enough. Thanks Dec 24, 2012 at 15:08

    Too general perhaps? 'Two weeks' is a time period also. But I understood the question to mean the individual units of measurement.

Their hypernym would be based in their singular aspect of similarity — into what set can they all fit. So words like time and span (or even time span) would do the trick assuming you mean a duration. If you mean a specific period then try, um, period.

  • Timespan is often spelled without the offending period: dictionary.reference.com/browse/timespan Dec 24, 2012 at 15:17
  • @WayfaringStranger Time-span is only, ever, and always spelt without any offending period. However, it is oft spelled with a graceful hyphen.

  • @tchrist Oops, meant offending space, which would make it two words. Dec 24, 2012 at 15:29
