The phrase "and more" is used to indicate that additional items, ideas, or quantities exist beyond those that have already been mentioned. It suggests an expansion of the list or description, implying that there is further information or additional examples available.
The phrase "and more" consists of the conjunction "and," which comes from Old English "and," meaning "and," and the word "more," originating from Old English "māra," which means "greater" or "additional." Together, they create a phrase that adds further information or items to what has already been stated.
