Usage note

The traditional rule of usage guides dates from the 17th century and says that to denote future time shall is used in the first person ( I shall leave. We shall go ) and will in all other persons ( You will be there, won't you? He will drive us to the airport. They will not be at the meeting ). The rule continues that to express determination, will is used in the first person ( We will win the battle ) and shall in the other two persons ( You shall not bully us. They shall not pass ). Whether this rule was ever widely observed is doubtful. Today, will is used overwhelmingly in all three persons and in all types of speech and writing both for the simple future and to express determination. Shall has some use in all persons, chiefly in formal writing or speaking, to express determination: I shall return. We shall overcome. Shall also occurs in the language of laws and directives: All visitors shall observe posted regulations. Most educated native users of American English do not follow the textbook rule in making a choice between shall and will. See also should.

Word Origin for shall

Old English sceal; related to Old Norse skal, Old High German scal, Dutch zal

usage

The usual rule given for the use of shall and will is that where the meaning is one of simple futurity, shall is used for the first person of the verb and will for the second and third: I shall go tomorrow; they will be there now. Where the meaning involves command, obligation, or determination, the positions are reversed: it shall be done; I will definitely go. However, shall has come to be largely neglected in favour of will, which has become the commonest form of the future in all three persons

Word Origin and History for shouldst

shall

v.

Old English sceal, Northumbrian scule "I owe/he owes, will have to, ought to, must" (infinitive sculan, past tense sceolde), a common Germanic preterite-present verb (along with can, may, will), from Proto-Germanic *skal- (cf. Old Saxon sculan, Old Frisian skil, Old Norse and Swedish skola, Middle Dutch sullen, Old High German solan, German sollen, Gothic skulan "to owe, be under obligation;" related via past tense form to Old English scyld "guilt," German Schuld "guilt, debt;" also Old Norse Skuld, name of one of the Norns), from PIE root *skel- (2) "to be under an obligation."

Ground sense of the Germanic word probably is "I owe," hence "I ought." The sense shifted in Middle English from a notion of "obligation" to include "futurity." Its past tense form has become should (q.v.). Cognates outside Germanic are Lithuanian skeleti "to be guilty," skilti "to get into debt;" Old Prussian skallisnan "duty," skellants "guilty."
