The Russian name for grandmother is babushka, a term used to address one's own grandmother as well as any woman of grandmotherly age. It is a somewhat informal but not impolite term. Since the Russian alphabet is different from the English one, transliteration is necessary, and words often exist in several different spellings. In the case of babushka, variations are baboushka, babouchka or babooshka. Russian nesting dolls are sometimes called babushka dolls. A related endearment is babulya.
