Learning objectives
By the end of this lesson, you should be able to explain the rules, recognise the target forms in context, avoid common errors and apply the patterns to new sentences.
- Understand the core terms and distinctions.
- Study examples in complete sentences, not as isolated rules.
- Complete all 15 practice items before opening the answer key.
1. Connectors express relationships
Connectors help readers follow the logic between ideas. Choose them for the relationship intended, not just because two words seem interchangeable.
2. Addition and contrast
Addition connectors include moreover, furthermore and in addition. Contrast connectors include however, nevertheless, whereas and on the other hand; their grammar and punctuation differ.
3. Cause and result
Because and since introduce reason clauses. Therefore, consequently and as a result link a result to a previous statement and often function as conjunctive adverbs.
4. Concession, condition and purpose
Although, even though and whereas can signal concession or contrast. If, unless and provided that express conditions. So that and in order to express purpose using different structures.
5. Punctuation and common errors
Do not normally join two independent clauses with a comma alone before however or therefore. Use a full stop, semicolon, or restructure the sentence. Avoid using two connectors that duplicate the same relationship.
Guided practice
Try each item first. Then open the answer key and read the explanation for any answer you missed.
- Choose the result connector: The roads were flooded; ___, school was closed.
- Choose the contrast connector: The task was difficult. ___, she completed it.
- Complete: We stayed indoors ___ it was raining.
- Correct punctuation: “He was ill, however he attended class.”
- Choose: ___ he was tired, he finished the work. (Although / Therefore)
- Choose the addition connector: The report is clear. ___, it is concise.
- Complete: We left early ___ we could catch the first train.
- Correct: “Because it rained, so the match was cancelled.”
- Choose: You may join us ___ you finish your work. (provided that / nevertheless)
- Which punctuation can link two independent clauses before “therefore”?
- Choose: He worked hard; ___, he did not win. (however / because)
- Complete: ___ the weather was poor, the flight departed on time.
- Choose the sequence connector: First collect the data; ___, analyse it.
- Correct: “She is poor, but nevertheless she is generous” if you want to avoid redundant contrast marking.
- Choose the cause connector: The event was delayed ___ the speaker arrived late.

Revision checklist
- I can explain the main rules in my own words.
- I can recognise the correct form in a complete sentence.
- I can explain why a common incorrect form is wrong.
- I can apply the rule to a new example.
If an answer was wrong, identify the rule behind the mistake and try writing two original examples.
