When Ψ -een (literally `why') is suffixed to a sentence in final position, the meaning is politeness with doubt and deference, and perhaps with a nuance of servility and/or obsequiousness. This is, of course, often used with caution or when great respect is being attempted. Compare:
×Âõ´¹Ô¶Á£ ¨ÞÅÂç ÂÖà Éâ »Ô¨ õ´ÄÔ?
venkadaacalam ngravaru viidu idu- taan- ngal-aa?
Is this the house of the man called Venkadaacalam?
×Âõ´¹Ô¶Á£ ¨ÞÅÂç ÂÖà Éâ »Ô¨ õ´ØĨ?
venkadaacalam ngravaru viidu idu- taan- ngal-een?
Might this be the house of the man called Venkadaacalam, if you don't mind my asking?
Note that Ψ -een occupies the place of the clitics so if the question is interrogative, it replaces the normal clitic È -aa.
