The pejorative suffix may add the sense of "a despicable example of the preceding," as in Spanish -ejo (see below). It can also convey the sense of "a despicable human having the preceding characteristic"; for instance, as in English -el (see below) or the development of the word cuckold from Old French cocu "cuckoo" + -ald, taken into Anglo-Saxon as cokewald and thus to the modern English word.
Examples of the pejorative suffix:
-ard, e.g. bastard (from Old French bast "pack-saddle", i.e. "child born in a pack-saddle")
-aster, e.g. poetaster, philosophaster (via Latin)
-el, e.g. wastrel (from "waste", i.e. "a wasteful person (pej.)")
-ista e.g. fashionista (sometimes used as a more '"playfully" pejorative than others, taken from Sandinista)
-nik, e.g. peacenik, neatnik (via Yiddish or Russian, where it is not necessarily pejorative)
-ea, e.g. poluea "seasickness" (from polu "wet)
-uxa (уха), e.g. černuxa, dramatic term for an unrelentingly bleak cinematic style (from čern- "black")
-ote(a), e.g. discursote "long dull speech" (from discurso "speech")
