I know both are used to mean the same thing and both are acceptable according to Oxford, but what I would like to know, as a confirmed hoorayer, is how do the hurrahers, pronounce their word when spoken out loud?
Iâm looking at you @Stella for the answer to this burning question.
BTW, Oxford also allows that:
Australianâ˘New Zealand
goodbye.
ââHooray George, promise youâll come back.ââ
and Iâm not sure about that, I seem to remember âhoorooâ being the operative word. Cue @toryroo
No idea what I was taught to say as a child⌠but I reckon itâs my years in France mixing, in the main, with French people that now influence how I speak
Iâll bellow a rousing âhurrahâ in public when appropriate (most recently at the commemoration for 8 May) and people around me seem to understand my emotions (and share 'em).
EDIT I now learn that my French pals are actually saying âhourraâ but who cares
Well if they say that, that settles it as to how you pronounce it. I have always said hooray, and spelled it accordingly, but no idea how I arrived at that conclusion. But the important thing is that all 3 of us understand it.
