What is Difference between "Ko" and "Ki"
की is a possessive, meaning "Raj's" or "belonging to Raj". And specifically it's the feminine form, since wife is feminine.
को means to/for (among other things) and you would use it for example to give something "to Raj".
Straying into the Jimmy Carr zone with this one.
