When the plural ends in “-ies”, how do I know whether the singular ends in “-y” or “-ie”? [closed]

my question is how am I supposed to recognize a singular form of a noun which plural form ends with “ies”? As you can see “cookies” are a “cookie” when singular, but at the same time “flies” stand for a “fly”. It seems there’s no rule for this, so I am rather asking for a list of exceptions if you will. Thank you.


It turns out that you don’t need to worry too much: it’s something in the order of 100 times more likely that the base word ends in -y.

Common exceptions are:

  • a few common monosyllabic words (“die”, “lie”, “tie”, “pie”) and compounds (“untie”, “underlie”…);
  • a few loanwords from French (“sortie”, “crêperie”, “cameraderie”…) plus one or two older loans that are now fairly well integrated (notably “calorie”)
  • a few informal words, which can actually often be spelt either way (“hippy/hippie”, “sweety/sweetie”, “movie”, “druggy/druggie”…)
  • the odd other word (“eerie”, “zombie”)

Overall, no need to lose too much sleep.
