I am very confused. Could you possibly elaborate (in detail) the reason why:
My object is to improve my English as much as possible. [WRONG it should be 'objective']
My object is to learn English. [RIGHT]
The object of the game is to improve children's math skill. [RIGHT]
So, why has Longman written the following:
! Do not use object to mean 'the thing you are working towards and hope to achieve'. Use objective: We have not yet achieved our objective (NOT our object).
Is Longman here wrong?
All of the expressions and examples which I have provided are extracted from Longman (see link below) and Common Errors from Longman too.
