Step 1: Identify the given sentence → “Do not eat the cake, wait your friends come.”
Step 2: Spot the error → The sentence is missing a proper conjunction between “wait” and “your friends come.” As it stands, the sentence is grammatically incomplete and awkward.
Step 3: Recall the correct usage → When expressing the idea of waiting until a certain action happens, the conjunctions “till” or “until” are used. Example: “Wait till the rain stops.”
Step 4: Apply the rule → In this case, the sentence should be corrected to: “Do not eat the cake, wait till your friends come.”
Step 5: Validate → Using “till” here makes the sentence grammatically correct and clear, while no other substitute (like “when” or “after”) fits as appropriately in the context.
Step 6: Apply the formatting instruction → The final answer must be written concisely without unnecessary spaces.
FinalAnswer:till
