Granddad or Grand-dad or Grandad?

Which is the correct spelling?

  • But don’t forget Grampa and Gramps or Gramma. All are common in the United States.

  • +1, I just stumbled upon the "grandad" spelling. It just doesn't feel right to me. But then again, I prefer the American spelling for most things.

According to Google NGram, in British English the spelling "grandad" is more popular than "granddad", however American English, the spelling "granddad" is more popular than "grandad".

American English:

British English:

Both exist, apparently.

The NOAD, says

granddad |ˈgranˌdad| (also grandad) noun informal - one's grandfather.

grandad |ˈgranˌdad|, Noun - variant spelling of granddad .

The OALD says the same thing, and is more specific, saying that "Granddad" is North-American English. If someone from U.S./UK can confirm, it would add more info.

    I don't have a copy of OED to confirm, but anecdotally I can confirm as a native en-gb speaker that I find the spelling with a double d marked. May 4 '11 at 12:40
  • @Peter Taylor: Thanks for your comment! So your point is that you, as a UK English speaker, would say "Grandad"?

    @Peter: I on the other hand (en-US) find the single-d spelling to be marked. May 4 '11 at 13:30

    @Alenanno, yes, I write "grandad" and pronounce it gran-dad. (For completeness, I write "grandpa" and "grandma" but the d is barely there when I say them). May 4 '11 at 13:33

    Thanks to both. So it confirms what I found... "Grandpa" definitely solves the dilemma though ahah :)

Further documentary evidence.

Clive Dunn's only #1 hit record, the famously ironic post punk single – Grandad, was spelled with one 'd'

In the UK, I've generally seen 'Grandad' used, particularly among the older generations containing a preponderance of grandads. So I'd say that's the correct spelling in British English, and from the other answers 'Granddad' appears to be more common is US English.

    Chambers Dictionary (which generally reflects BrE) gives both alternatives, with grandad first (which is how I've always spelt it).

  • The spelling appears illogical but similar things happen in other languages e.g. Grand-Rue and Grand-Place in French, when both words are feminine and would normally take the feminine form of the adjective. Jul 21 '15 at 7:04
