However and whereas: contrasts with clear sentence structure

The idea

Whereas and contrastive while link clauses within a sentence. However meaning «nevertheless» links ideas across sentences or after a semicolon: It is small; however, it is useful. But can also connect words, as in warm but heavy.

Examples

• The blue bag is waterproof, whereas the red one is not.
• The café is small. However, it has a large terrace.
• The route is longer; however, it avoids the steep hill.
• Mina prefers quiet cafés, while Omar likes lively ones.
• Whereas the morning ferry carries cars, the evening ferry takes only passengers.
• The jacket is warm but heavy.

Watch out

In standard edited writing, do not join two complete clauses with only a comma before however. Use a full stop or semicolon. Whereas does not stand alone as However, ... does; while can also refer to time.

Try it yourself

   whereas

   Whereas links the contrasting clauses within this sentence. The comma alone would not support however here.

2. Choose the correct option. The café is small. ___, it has a large terrace. (However / Whereas)

   Show answer or example answer

   However

   However, introduces a complete new sentence. Whereas would require a main clause to complete its construction.

3. Choose the correct option. The jacket is warm ___ heavy. (but / however)

   Show answer or example answer

   but

   But joins the two adjectives warm and heavy. Contrastive however cannot replace it in this structure.
