How to learn French grammar more easily?

There is no easy way to learn French grammar. The Academie Française was invented as an administrative measure by the Richlieu dictatorship in the mid-17th century to codify the usage of Parisian aristocratic salons, whose hostesses deliberately choose knowledge of the more recondite features of French grammar to divide the preferred expensively educated "goats" among their prospective guests from the general nondescript "sheep" of the hoi polloi. The language itself had originally been an adoption by the invading, Dutch-speaking Franks of the dog Latin of the semi-romanized towns of Gaul as an administrative language that ex-Roman province where Gallic aka Gaulish, a relative of Welsh, was still the normal language of the countryside. The Dutch-like nature of Old French was gradually affected (and phonetically revolutionized) by internal migration of the upward socially mobile from the countryside, a process that had reached its zenith precisely as the modern language was being normalized by these aristocratic grandes dames. The result is an ad hoc, inconsistent and indeed chaotic mélange with snobbery and obfuscation as its only guiding principles. If you want an easier grammare, try a language other than French: almost any will do, from Basque to Finnish...
