Chinese wtiting and language has undergone many reforms. The pictograms were standardised when China was first unified under the Qin, to create a language of officials for unified administration. Up to the introduction of a simplified character set by the People's Republic of China in the 20th C.
When the territory that becane Spain was united under the Castillian Crown, the romance vernacular associated with the polity of the royal house became increasingly used in instances of prestige and influence, and the distinction between "Castilian" and "Spanish" started to become blurred. Hard policies imposing that language's hegemony in an intensely centralising Spanish state were established from the 18th century onward.
As well as the suppression of minority languages, France have a body that rules on official correct use of language, L'Académie française. Their mission since 1635 has been to “give certain rules to our language and to make it pure, eloquent and capable of dealing with the arts and sciences”. In particular they have sought to eliminate loanwords, by generating French language constructions to replace them.
There are movements including in French, to reduce or eliminate grammatical gendering, see
Gender neutrality in languages with grammatical gender.
English is an especially mongrel language, as I think nicely illustrated in this meme. Although only the third most spoken language, that computer coding and Hollywood films are largely in English gives it a particular role as a modern lingua franca. Samuel Johnson's dictionary published in 1755 led to increasing standardisation of spelling and common vocabulary. Various style guide, or style manual have sought to provide clarity or standardisation in particular writing disciplines, like journalism or scientific publishing. Recieved Pronunciation was a particular standardisation of English used for a long time across national radio broadcasting, which has had a lasting impact. I like the history of 'ok', which apparently started out as a concise jornalistic signoff for telegraph use, from the joke 'ol korrect' where the phrase ironically undermines itself through being mispelled, and has gone on to be a term used around the world.
George Orwell provided a fictional thought experiment about the power of controlling language on controlling thought, in his appendix to 1984 on 'Newspeak'. While the research does not tend to support this view of hard linguistic determinism, it is an important warning against motivations to coerce language change for ideological or propagandistic purposes.
I would also say it can be difficult to tease out exactly what our language is doing, and why it is the way it is. 'Shall' comes from Skuld, who was one of the Norns who are the Norse cognates of the Greek Fates, who spin people's futures along with Verthandi ('becoming' or 'in-the-making), and Urthr/Wyrd (fated). These kind of framings of the ways in which the future is coming to be even in our simplest words and grammar, can have subtle influences on how we understand the mechanisms of the world, and for instance how open people have been to physicalist-materialism. The concept of freewill explicitly arises from addressing the Problem of Evil, but whether or not people are likely to think we have it is going to depend on how people frame causality, which is influenced by linguistic mechanisms.
Poets frequently investigate the subtle effects of particular language, and adopt antique or idiosyncratic modes, illustrating how bending rules can relate directly to creative practice. I think that relates to Wittgenstein's maxim
"For a large class of cases—though not for all—in which we employ the
word "meaning" it can be defined thus: the meaning of a word is its
use in the language."
-Philosophical Investigations, section 43.
Language is changing all the time, in relationship with the changes in our modes-of-life. The community if language users are open to influence, by pursuasion, by example, through literature memes and humour. If you wish to advocate a specific reform for clarity and consistency, it's on you to recruit others to your view, specifically by making the case current use is problematic. People all the time have been updating language, in response to such cases. Language is not crystalised, it is on a journey, with us:
“Language is the road map of a culture. It tells you where its people
come from and where they are going”
-Rita Mae Brown
Language organises our experiences, abd places ideas in specific proximities.
“A different language is a different vision of life.”
— Federico Fellini
But it goes beyond simply conveying data. It is like the water we swim in, the air we breathe, and:
“Language is the blood of the soul into which thoughts run and out of
which they grow.”
― Oliver Wendell Holmes
