Is there a word that can used like decade, but when talking about units not years?

For example, everyone knows that:

  • 2006 is within a decade of 1998
  • 1989 is in the same decade as 1984

However, when you try to do the same for units, it's not so easy:

  • 45 is within ten of 38 (sounds a bit weird, but is acceptable)
  • 76 is in the same ten as 74 just doesn't sound right at all!
  • 1
    Wikipedia: "A collection of ten items (most often ten years) is called a decade." – mplungjan Oct 27 '14 at 12:20
  • aside from decade itself, when one is needed a new word is coined. For example, percentile when discussing groups of percentages. – Oldcat Oct 27 '14 at 18:47
  • "Within ten of" is completely fine. That doesn't sound weird at all. – DCShannon Feb 2 '16 at 20:11

Unlike some Romance languages, there isn't such word in English. When we talk about countables, however, we can always say...

dozen - (noun) "A group of 12 people or things": A dozen oranges, half a dozen doughnuts (6 doughnuts). ("dozens of" = a large number of people or things)

score - (noun, plural same) "a group of 20 things, often used in combination with a cardinal number e.g. fourscore = 80)": A score of men lost their lives in the battle.


Although some dictionaries define "ten" as "something having 10 units or members" You couldn't possibly say: "I'm buying two ten apples or half ten oranges.
