Aoa Yes in modren usage it correct as after objections from feminists and liberals etc this linguistic change has become a routine. But here in Pakistan we are still using "Everybody must do his duty." whereas American and English speakers say "Everybody must do their duty." Once it was suggested to use "Everybody must do his/her duty." but again it was cumbersome for typists/writer/composers and plural pronoun instead has come to stay! Teachers of English must read and follow latest linguistic trends and books. Naeem Raza
