kitschy (adj.)

1926, from German kitsch, literally "gaudy, trash," from dialectal kitschen "to smear." Earlier as a German word in English.

What we English people call ugliness in German art is simply the furious reaction against what Germans call süsses Kitsch, the art of the picture postcard, and of what corresponds to the royalty ballad. It has for years been their constant reproach against us that England is the great country of Kitsch. Many years ago a German who loved England only too well said to me, 'I like your English word plain; it is a word for which we have no equivalent in German, because all German women are plain.' He might well have balanced it by saying that English has no equivalent for the word Kitsch. [Edward J. Dent, "The Music of Arnold Schönberg," "The Living Age," July 9, 1921]

adjective suffix, "full of or characterized by," from Old English -ig, from Proto-Germanic *-iga- (source also of Dutch, Danish, German -ig, Gothic -egs), from PIE -(i)ko-, adjectival suffix, cognate with elements in Greek -ikos, Latin -icus (see -ic). Originally added to nouns in Old English; used from 13c. with verbs, and by 15c. even with other adjectives (for example crispy). Adjectives such as hugy, vasty are artificial words that exist for the sake of poetical metrics.
