> Grammar and sentence structure are but mear suggestions
Learning French has been eye opening, in that many grammatical structures that are optional in English are compulsory in French. Abbreviations for example: “it is” or “it’s” are both valid in English, but in French you’re not supposed to say “ce est”, you have to say “c’est”.
English has places where one or the other is preferred. For example one, would normally write, “It is with great regret…,” without the contraction. It’s not a hard rule, more a matter of register. Similarly, in the preceding sentence, “it is” would seem overly formal.
Damn French, they ruined French!

English is the only big language that doesn't have a recognized standardization body.
