Shall versus Will
People may sometimes tell you that there is no difference between shall and will, or even that today nobody uses shall (except in offers such as "Shall I call a taxi?"). This is not really true. The difference between shall and will is often hidden by the fact that we usually contract them in speaking with 'll. But the difference does exist.
The truth is that there are two conjugations for the verb will:
1st Conjugation (objective, simple statement of fact)
Person ____ Verb _____ Example _________________ Contraction
Singular :
I ______ shall _________ I shall be in London tomorrow.__________ I'll
you ____ will _________ You will see a large building on the left.____ You'll
he, she, it ___ will ________ He will be wearing blue. _________ He'll
Plural :
we ______ shall _____ We shall not be there when you arrive. ___ We shan't
you _____ will ______ You will find his office on the 7th floor. ______ You'll
they _____ will ________ They will arrive late. ___________________ They'll
2nd Conjugation (subjective, strong assertion, promise or command)
Person _____ Verb ______ Example __________________ Contraction
Singular :
I _______ will ___________ I will do everything possible to help. _________ I'll
you _____ shall _________ You shall be sorry for this. ________________ You'll
he, she, it ____ shall ________ It shall be done._______________________ It'll
Plural :
we _____ will ___________ We will not interfere. __________ We won't
you _____ shall __________ You shall do as you're told. ______ You'll
they ____ shall __________They shall give one month's notice. ____ They'll
It is true that this difference is not universally recognized. However, let those who make assertions such as "People in the USA never use 'shall'" peruse a good US English dictionary, or many US legal documents which often contain phrases such as:
Each party shall give one month's notice in writing in the event of termination.
Note that exactly the same rule applies in the case of should and would. It is perfectly normal, and somewhat more elegant, to write, for example:
I should be grateful if you would kindly send me your latest catalogue.
