Umb.. I think its a tamil word
Kathai Aankhon Wali
Katha in Hindi = Kathai in Tamil = Kathe in Kannada = Katha in Telugu = Story / Tale in English
kathai in tamil means a tale or story.
kathai, is a word made from the word ‘katha’.
Katha is used in paan. along with with choona. Paan is made with kathaa-choona. and other spices.
Whereas choona is white in colour. katha is dark brown. almost chocolate colour.
so kathai aankho-waali ladki means, girl with chocolate-colour eyes.
IT MEANS THE COLOUR OF KATHA…WHICH IS LIGHT BROWN OR HAZEL!
