I am looking for a word that denotes a word composed of at least two parts, at least one of which is from a different language than the other(s); a word with mixed etymology.
An example is antimatter
where we have the Greek prefix for not, anti-
, with the Latin word for substance, māteria
.
If pressed, I might suggest "bastard word" for these specimen, but it does not sound quite right. Other examples of such words are also much appreciated!
