A's and An's going before words aren't the only things that are apart of grammar.

Its and It's - It's is reffering to the possession of a noun, aka a contraction. Such as "It's trying to eat that fruit over there". Its is used mostly for land description, such as "Its so beautiful". The concept of its and it's is really hard to describe, though, and I don't think I'm quite explaining it right :P

Punctuation - You generally don't want to overruse this. Only use commas when you need them. If you have "The dog says bark woof and yip", you need commas in "The dog says bark, woof, and yip". Also, try not to totally drag on sentences with commas.

Semicolons should be used only sometimes. "-" goes well with replacing semicolons as well. If a sentence comes at a point where there's a colon and it also goes with a comma, use the semicolon.

Plurals - Aka, more than one thing. Not every word is pluralized with an "s". Obsidians, Bedrocks, and Dirts are examples. It's like sheep; the plural for sheep is just sheep, not sheeps. Though, Diamonds and Emeralds can be pluralized with an S.

If the word ends with a y, then the plural for it is "ies" most commonly. The plural for puppy is puppies, not puppys.

Capitalization - You capitalize the first letter of the first word of every single sentence and line of dialogue. Don't neglect this rule, ever.

Proper Nouns - Always, always, always capitalize proper nouns. Creepers are not proper nouns, and neither are skeletons or zombies. Names of things, however, are proper nouns, like Keeba or Dreitharicus. Places are also proper nouns, like Washington D.C.

There is one exception to making nouns proper when they shouldn't be proper, though. When you're making a story from a dim-minded creature's perspective, sometimes they will think of things proper enough to be capitalized, and thus you can write around this rule.

There's a lot more to grammar than even that, but I am too lazy to write it all down. :/
