There exist many different ways to express the act of giving someone money in advance. Instead of saying "front someone some amount of money," you may consider using the phrase "lend some funds," "provide an advance," or "advance some cash." Other alternatives may include "loaning some money," "giving a prepayment," or "providing a down payment." Each of these phrases aims to convey the same meaning as fronting someone money, but with slight differences in tone and formality. By choosing an appropriate synonym, you can effectively communicate your intentions and expectations to the recipient of the funds.
