10 Basic English Grammar Rules That You Need To Know

1. Just only use capital letters for appropriate nouns and at the first of a sentence.
2. In every sentence, there should be one noun and one verb at the same time. A sentence with more than one noun or verb is always confusing to understand at all.
3. When a sentence will complete, just use appropriate punctuation. So there is no need to have dual punctuation when finishing a sentence. If an apostrophe is needed you have to make sure to use it to show your ownership. An apostrophe is also used when words are shortened.
4. Whenever writing other multiple sentences about the same subject or line you thought about, just use paragraphs to distribute long segments of writing.
5. When linking two lines of thought of a sentence, you should use a conjunction to make things or make better sense.
6. Do not try to end a sentence with a preposition.
7. The sentences should be completed thoughts and not wreckages.
8. The conjunction word should not be used to start of a sentence.
9. Don’t try to use double negatives. Such as- no, not and never.
10. Always avoid repeating lines of thought in a sentence.
