Proposition and sentence are two separate entities indicating their specific purposes, definitions and problems. A
proposition is a logical entity. A proposition asserts that something is or not the case, any proposition may be affirmed or
denied, all proportions are either true (1’s) or false (0’s). All proportions are sentences but all sentences are not
propositions. Propositions are factual contains three terms: subject, predicate and copula and are always in indicative or
declarative mood. While sentence is a grammatical entity, a unit of language that expresses a complete thought; a sentence
may express a proposition, but is distinct from the proposition it may be used to express: categories, declarative sentences,
exclamatory, imperative and interrogative sentences. Not all sentences are propositions, propositions express sentence.
Sentence is a proposition only in condition when it bears truth values i.e. true or false. We use English sentences governed
by imprecise rule to state the precise rules of proposition. In logic we use sentence as logical entity having propositional
function but grammatical sentences are different from logical sentences while the former are having only two divisions
namely subject and predicate and may express wishes, orders, surprise or facts and also have multiple subjects and
predicates and the latter must be in a propositional form which states quantity of the subject and the quality of the
proposition and multiple subjects and multiple predicate make the proposition multiple.
