At this level, you will see when used in conditional-like structures. It adds nuance to your storytelling, allowing you to layer events precisely within a narrative flow.
Advanced users employ when to create sophisticated relative clauses. It can also be used in more abstract, philosophical contexts to describe conditions or states of being, moving beyond simple temporal markers.
Mastery of when involves understanding its subtle role in literary devices and formal argumentation. It can be used to set a scene or establish a causal link that feels both temporal and logical, showing deep control over sentence structure.
