* More indicates a greater quantity or degree than another.
* Most indicates the greatest quantity or degree among several.
Therefore, "more" and "most" don't have "greater meaning" on their own. Their meaning depends on the context they are used in.
For example:
* "I have more books than you." ("More" here refers to a larger quantity of books)
* "This is the most beautiful sunset I've ever seen." ("Most" here refers to the highest degree of beauty)
The meaning of "more" and "most" is determined by the noun they modify and the context of the sentence.
