Question

what is the full form of MRS

Answer 1

We seldom, if ever, write them out infull – and most of us probably never stop to think what the full versions of these words are. It may come as a surprise that 'Mr' and 'Mrs' aren't actually short for mister and missus – they were originally abbreviations of master and mistress.
