Oh gosh am I going to blush if I get this wrong.

Okay, the things you're asking about are nouns.

There are proper nouns which refer to a specific person, place, or thing - Monday, Sunday, April, May, Winter, Abraham Lincoln, Jamaica - as some examples. ALL proper nouns are capatalized.

Also, there are "common nouns" which is referring to a person, place, or thing in a general sense, such as...
"town, sign, boy, girl, people, moose, road, mustard."
Those things are only capitalized if they are at the beginning of a sentence.
Words like north, south, east, and west are common nouns and are only to be capitalized when a part of a name such as "Western Europe."


The one I'm unsure about are the seasons - I don't think seasons are to be capitalized, but I'm not sure if that's correct or not.

Hopefully I didn't confuse you at all.
