Which is the correct term “iced tea” or “ice tea”?
The original drink which was popularized in the early 1900’s was called “iced tea”, but today the way many English speakers pronounce it more closely resembles “ice tea”. The term “ice tea” has even began to shows up regularly in writings and edited publications.
Other similar terms like “iced cream” and “iced water” have evolved into “ice cream” and “ice water” over the years. So much so that people would no doubt give you a funny look if you asked for “iced cream” today.
For now it seems that both “iced tea” and “ice tea” are acceptable, but we will have to wait and see if “iced tea” succomes to the same fate as “iced cream” and “iced water”.
