You may think that capitalizing nouns is a trivial (not important) grammar rule. However, poorly capitalized words are a quick giveaway that you haven’t quite mastered English writing. Proper capitalization helps your writing look professional, tidy and correct.
The bad news is that it’s really just a matter of memorizing capitalization rules.
The good news is there’s not much to memorize. Here are the three fundamental rules you can use to remember which words get capitalized in English:
Example – The man jumped over the hill.
For example: Matthew, Helen, France, Tokyo, Mississippi, Microsoft, Saturday, January
For example – Mr., Mrs., Ms., Miss, Doctor (Dr.), President, Lord
