B1 English GrammarComplex Sentence Structure
Combine multiple clauses fluently using advanced connectors like although, despite, whereas, unless, as long as, and provided that.

| even though | start of clause | Even though he's rich, he's unhappy. |
| however | between clauses | It rained. However, we went out. |
| nevertheless | between clauses | He failed. Nevertheless, he tried again. |
| whereas | connects clauses | I like tea, whereas she likes coffee. |
