through; by way of; after; via ~
Expresses that something happens after passing through a period, place, or process, meaning 'through', 'by way of', or 'after'.
を経て is a formal, written-style expression. It indicates that something occurs after going through a certain period or process. For example, you can say that after years of training (長い訓練を経て), someone becomes a professional. It's similar to saying 'after going through' or 'by way of' in English. The key point is that there is an intervening stage or experience that leads to the final result. It is often used in resumes, biographies, or historical accounts. Because it's formal, you'll rarely hear it in casual conversation. If you want to say 'after two years' in a casual way, you'd say 二年後に, not 二年を経て.
