What it means
たら expresses a condition or a time relationship. Depending on context, it can mean “if,” “when,” or “after.” It is formed from the past form of a verb, or from the appropriate past-style form of a noun or adjective, followed by ら. The result clause describes what happens if or when the condition is fulfilled. For a sequence of events, たら often means “after,” as in “after I finish.” The condition clause normally comes before the result clause.
Usage note
たら can describe either a hypothetical condition or a real event that is expected to happen, so the exact English meaning depends on context. Do not confuse it with なら, which usually presents a topic or condition based on information already established.
