Analysis of information sources in references of the Wikipedia article "Honorifics (linguistics)" in English language version.
For example, Hindi and Bengali have a three-way distinction [of familiarity and politeness]—Hindi ap, Bengali apni "you" are polite or honorific forms; Hindi tum, Bengali tumi are informal forms; and Hindi tū, Bengali tui are used only for inferiors and small children. (Hindi and Bengali differ, however, in the plural forms of these.) In Gujarati, on the other hand, tū~ is a very familiar pronoun, whereas təme is used generally, covering the approximate domains of Hindi ap and tum; ap, if used, strikes the hearer as fawning. Marathi has a similar system.
