Here are two useful resources for writers:
1- The Dictionary of American Regional English (DARE)
"Different words may be used to designate the same thing depending on the region. It’s important to consider this and use the right word to make the writing authentic."
(Nika Paradis - Medium)
2 - The Compleat Lexical Tutor
"Looking up how to use a word in a sentence isn’t as easy as finding how it’s spelled."
