Agracier--That's why we need the language police!
You can't go by "what a word means to you".
I never said anything about a personalized language. That would be a recipe for total incomprehension.
But however, languages do evolve and often right before our eyes. So when a sizable minority of people by or for whatever manner (unconsciously perhaps) decide to change or add or slightly alter meanings of words, then those changes become valid.
When I was young, I watched more than enough 'Our Gang' shorts where Alfalfa tries to 'make love' to Darla and become her 'lover'. Abbott and Costello also used these words in the same older fashion, and yet somewhere between my younger days and now, poof ... there is a whole new connotation to the words. How wonderful and also how comically archaic the old meanings sound.
In 'Tipperary', a 100 year-old classic song by next year, the dim-witted Irishman, Paddy-O, comes to London and thinks 'everyone is gay'. Which even at the time was a word undergoing a shift in meaning from simply happy, to living a fun life to being of loose morals and promiscuous. And now there's yet another completely new meaning added. This is part of the reason why jokes based on the meaning of words are more prevalent in English than in other languages.
You'd never get these kind of developments under a language police. And the mild anarchy found in English is part of what makes English such a fun and complex and varied language to use. Where I live, the Dutch language is (in theory) regulated by a commission of wise and learned and undoubtedly well-meaning, but out-of-touch group of academics who make proposals to improve Dutch which are then voted into law by the parliaments of Belgium and the Netherlands. And in France there is the old fuddy-duddy Academie Francaise which is supposed to guard the classic purity of the French language. Don't tell me that a red blooded American aspires to any of these kind of institutions ... ha ha.
Spelling is another matter, even though that too evolves. But even so ...
Bill Bryson gives a hilarious and yet sympathetic history of English in several of his earliest books. They are full of accounts about well-meaning control-freaks who wished to regulate and order English into some semblance of rationality, but ultimately all bit the dust.
You're lucky that no one regulates English. Compilers of dictionaries can only observe usages and report on how widespread particular usages and meanings are. They don't regulate or give out citations.
