A pejorative suffix is a suffix that attaches a negative meaning to the word or word-stem preceding it. There is frequent overlap between this and the diminutive form.
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:
-alla -alles Suffixed to nouns gives new nouns. Examples: gentalla (from gent "people"). It's also used as a collective (group) suffix.
-arro -arros (fem. -arra -arres) Suffixed to nouns gives new nouns. Example: veuarra (from veu "voice"). It's also used as an augmentative suffix.
-astre -astres (fem. -astra -astres) Suffixed to nouns gives new nouns. Example: poetastra (from poeta "poet"). This suffix has also the meaning "indirect relation with".
-ot -ots (fem. -ota -otes) Suffixed to nouns gives new nouns. Example: sabatot (from sabata "shoe"). Suffixed to adjectives gives new adjectives. Example: lletjot (from lleig "ugly"). As a suffix it also means "object", giving a lexicalized word.

-婊biǎo,e.g.绿茶婊lǜchábiǎo(used to describe a lascivious girl who pretends to be innocent,from 绿茶lǜchá"green tea",which symbolizes innocence) NOTE:this suffix is from the word 婊子biǎozi"prostitute",so at first word suffixed with 婊 were used to describe only women,but recently it can be used to describe both men and women,for example,圣母婊shèngmǔbiǎo,which means people who pretend to bo as merciful as goddesses on the Internet,from 圣母shèngmǔ"goddess"
