When learning English, it is important to be careful about special conjunctions as well as tenses. Two most commonly used conjunctions are “when” and “while”. While “when” conjunction has the meaning of a completed action, “while” is more like a sustained action.
Generally, both “when” and “while” conjunctions are related to past tense. Whereas “while” emphasizes an act in certain times or continues in a determined time frame, “when” is used for actions in the past that do not last or instant actions.
