Q: Have you noticed the death of the “-ed” adjective? I see lots of signs that say “ice tea” and people talk about “mix tapes.”
A: No, we haven’t noticed the death of the “-ed” adjective, though some words that began life with the suffix are often seen without it.
For example, the use of “damned” as an adjective to express disapproval or add emphasis showed up in the late 16th century, while “damn” used in this sense didn’t appear until the late 18th century and is now much more popular.
The loss of the “-ed” ending here is is no surprise. The fact is that “-ed” can be awkward to pronounce before a consonant. This can sometimes lead to its loss in writing. For example, “ice cream” and “iced cream” both appeared in the 17th century, but only the “d”-less version has survived.
As for the chilled tea served over ice, both “iced tea” and “ice tea” showed up in the 19th century (the version with “d” in 1839 and one without it in 1842, according to citations in theOxford English Dictionary). You can find both versions in standard dictionaries now, though the suffixed one is far more popular.
A search of the News on the Web corpus, a database of online newspaper and magazine articles published since 2010, shows that “iced tea” is five times as popular as “ice tea.” And the longer version is even more popular in a search with Google’s Ngram viewer, which tracks words and phrases in digitized books up until 2008.
In short, the “-ed” adjective is alive and well in writing, though it’s often dropped in speech. We’re used to hearing things like “corn beef,” “mash potatoes,” “grill cheese,” “chop liver,” and “whip cream,” but people generally preserve the “-ed” endings in writing these noun phrases.
As for the compilation of music from multiple sources, it’s usually “mixtape” now, though it was “mix tape” when it showed up in writing in the 1980s and has sometimes been “mix-tape,” according to our searches of newspaper databases. It has seldom been written as “mixed tape.” The word “mix” in the compound “mixtape” is an attributive noun—one used adjectivally.
