Final answer:
In English, capitalization before a comma depends on the rules of capitalization for the specific word.
Step-by-step explanation:
In English, we do not always use a capital letter in a word used before a comma. It depends on the specific rules of capitalization for the word in question. For example, proper nouns are typically capitalized regardless of their position in a sentence. However, common nouns are not capitalized unless they are specifically at the beginning of a sentence.
