Quick answer: A sinking fund prepares for a known or reasonably expected future expense; an emergency fund protects against important, unexpected financial shocks.
Sinking funds are for expected costs
Examples can include car maintenance, holidays, annual insurance premiums, travel, home maintenance, or a planned replacement purchase.
Emergency funds are for shocks
Job loss, an urgent repair, unexpected medical costs, or another necessary and time-sensitive expense may fit the emergency category depending on circumstances.
Why the distinction helps
Saving separately for predictable costs reduces the chance that routine expenses repeatedly drain the emergency reserve.
