Hello Everyone

,
This Is A Really Confusing Issue In The Conetxt Of Modern Day English! As Far As I Know, In The U.s., 'shall' Is Losing Its Relevance Day By Day. But For People Who Embrace English In Its True Essence, Opine That 'shall' Expresses An Extra Degree Of Determination And Conveys The Intention Towards Something Espescially Of The First Person [singular Or Plural] In Case Of A Communication. THIS IS BASED ON MY LIMITED GRIP OVER THE LANGUAGE.ANY ENHANCEMENT OR CORRECTION IS WELCOME.
