The problem is not about making mistakes from time to time. First of all, it happens to everybody, even the best ever master of a language. Secondly,
even if sometimes you didn't mean to write something, there's just what happens to be "typo", the keyboard key that skipped or was doubled,
My mother language is not English. It is French. (and to those who start about it, yes I take some well-placed pride in mastering the languages I
speak and write)
The problem is about people who suck so bad at writing that getting their point is a challenge. Whatever language is their mother language. I reckon
that some mistakes are so obvious that people recurrently doing them must either be terribly illiterate, amazingly lazy, or simply provocative. How
could someone ever write "there" instead of "their" or "they're" ? It is lazy or stupid, sorry. Change it to "here" and the sentence doesn't
mean anything anymore. Or as another example, "here" and "hear". Or "your" and "you're".
"I'm waiting to there from you."
"Oh, I'm waiting to hear from you. Sorry. Well it's the same no?"
"Here on here way."
"Oh, they're on their way. Sorry. Well it's the same no?"
See how stupid this can be?
The next thing is: punctuation. Have you ever tried to read a block of 40 lines without a single comma, period or anything like that? It is
impossible. Yet some people persist in writing huge sentences without any sort of punctuation, particularly in English, and it makes it incredibly
difficult to follow. The other common mistake is to add punctuation where it is unneeded.
People who can't write properly are people who can't understand properly what they read.
Some years ago, I found somewhere on the internet this fantastic "How to write gooder" guide
I can't remember where, but saved it to my
computer. Here are then the awesome recommendations of it:
• Avoid "overuse" "of" "quotation marks" !
• Also too, never, ever, ever be redundantly repetitive; basically don't use more words than are essentially necessary; it's highly superfluous.
• Also, always avoid all awkward and affected alliteration.
• Always pick on the correct idiom.
• Analogies in writing are like feathers on a snake.
• And don't start a sentence with a conjunction.
• Avoid clichés like the plague, they're old hat.
• Avoid trendy locutions that sound flaky.
• Avoid using sesquipedalian words.
• Be carefully to use adjectives and adverbs correct.
• Be more or less specific.
• Bee careful two use the write homonym.
• Comparisons are as bad as clichés.
• Contractions aren't necessary and shouldn't be used.
• Corect speling is esential.
• Do not put statements in the negative form.
• DO NOT use exclamation points and all caps to emphasize !!!!!!!
• Don't never use no double negatives.
• Eliminate commas, that are, not necessary, parenthetical.
• Eschew ampersands & abbreviations, etc.
• Everyone should be careful to use a singular pronoun with singular nouns in their writing.
• Exaggeration is a billion times worse than understatement.
• Foreign words and phrases are not apropos.
• Hunt High and Low and Go around the barn at high noon to avoid colloquialisms.
• Hyphenate between sy-llables and avoid un-necessary hyphens.
• If any word is improper at the end of a sentence, a linking verb is.
• If you've heard it once, you've heard it a thousand times: Resist hyperbole; not one writer in a million can use it correctly.
• It is wrong to ever split an infinitive.
• Never use a big word when a diminutive one would suffice.
• No sentence fragments.
• One should NEVER generalize.
• One-word sentences? Eliminate.
• Only Proper Nouns should be capitalized.
• Parenthetical remarks (however relevant) are (usually) unnecessary.
• Perform a functional iterative analysis on your work to root out third generation transitional buzzwords.
• Place pronouns as close as possible, especially in long sentences of 10 or more words, to their antecedents.
• Prepositions are not words to end sentences with.
• Profanity is for assholes; it makes writing crappy.
• Proofread carefully to see if you any words out.
• Puns are for children, not groan readers.
• Take the bull by the hand and avoid mixing metaphors.
• The adverb always follows the verb.
• The passive voice should never be used.
• Understatement is always the absolute best way to put forth earth shaking ideas.
• Use hyphens in compound-words, not just where two-words are related.
• Use the apostrophe in it's proper place and omit it when its not needed.
• Use words correctly, irregardless of how others use them.
• Verbs has to agree with their subjects.
• Who needs rhetorical questions?
• Words however should be enclosed in commas.
• Writing carefully, dangling participles must be avoided.
To conclude very simply: read
again what you have written. Give it time. You'll improve naturally.
