How do you spell cooperate?

[DarkLightA]

co-operate or cooperate?

 

[nyota]

Both are correct.

 

[5jj]

co-operate or cooperate?

I use the hyphen, but both ways are fine.

 

[BobK]

co-operate or cooperate?

Either; it's also possible (in older books) to find it with a diæresis over the [STRIKE]first[/STRIKE] second* o, but I don't know how to type that. It looks a bit like an umlaut, but it's not the same.

Until recently, I was keeping a collection of editions of the same dictionary, so I could trace this sort of evolution. But there's a limit to the number of old books that MrsK will tolerate. ;-)

*Coolfootluke kindly corrected me in a PM, thinking to spare my blushes. But I can take it ;-)

Afterthought: but whatever you do don't tolerate hyphenation programs that let you put "co[-]oper-"
at the end of a line and start the next with 'ate'.

(Other hyphenation black spots are "therapist" and "legend". ;-))
