"立て替える" means to pay money on behalf of someone else or to pay in advance with the expectation of being reimbursed later. It is often used in situations where one person covers expenses temporarily for another, such as meals, travel costs, or bills.
Common Contexts
This verb is frequently used in social and business settings when discussing expenses that will be settled later. For example, friends might use it when one pays for a group meal, or employees might use it when covering company expenses before reimbursement.
Collocations and Patterns

Register and Politeness
"立て替える" is neutral and can be used in both casual and formal contexts. However, in very formal business communication, more polite expressions might be preferred.
Common Mistakes
Learners sometimes confuse "立て替える" with "貸す" (to lend). The key difference is that "立て替える" involves paying someone else's expense upfront, expecting reimbursement, while "貸す" means giving money or items temporarily without immediate payment involved.
