Yiddish and Russian (Yiddish, from Russian), of Slavic origin.(American Heritage® Dictionary of the English Language, Fourth Edition)
From the Slavic suffix (Russian: -ник (-nik)). This suffix experienced a surge in English coinages for nicknames and diminutives after the 1957 Soviet launch of the first Sputnik satellite. English usage is heavily influenced by Yiddish usage of -nik and similar borrowed words (nogoodnik, nudnik, kibbutznik). (Wiktionary)
