There is no agreement among the accountants as regards the basic concepts of accounting. There is no uniformity in generally accepted accounting principles (GAPP). The terms-axioms, assumptions, conventions, concepts, generalizations, methods, rules, doctrines, techniques, postulates, standards and canons are used freely and inconsistently in the same sense.
"A general law or rule, adopted or professed as a guide to action, a settled ground or basis of conduct or practice." This definition given by dictionaries comes nearest to describing what most accountants mean by the word 'Principle'. Care should be taken to make it clear that as applied to accounting practice, the world principle, does not connote a rule for which there can be no deviation. An accounting principle is not a principle in the sense that it admits of no conflict with other principles
