English — Contrast: while / whereas
Both while and whereas join two clauses that contrast, as in He likes tea, whereas she prefers coffee. While has a second job too: it marks two actions happening at the same time.

How it works
✓ Rule
To contrast two facts, put whereas or while at the start of the clause it introduces: Whereas the north is cold, the south is warm; The old model was slow, while the new one is fast. For simultaneous time, use while with a continuous verb: While I was cooking, the phone rang.

Good to know
⚠ Note
whereas only means contrast — it can never mark time, so While I was cooking is fine but Whereas I was cooking is wrong. When either linker opens the sentence, separate the two clauses with a comma: Whereas the north is cold, the south is warm.
