Contrast is one of the most important logical relationships in both spoken and written English — we use it to acknowledge difficulties, explain unexpected results, and present balanced arguments. However, the words used to express contrast belong to two different grammatical families that teachers often treat as interchangeable: conjunctions (although, even though, while, whereas), which join clauses within a sentence, and connectors (however, nevertheless, on the other hand), which link ideas across sentences. Confusing these two families produces consistent errors in punctuation and structure. This lesson gives teachers a clear map of the contrast system and the knowledge to explain it precisely. Cross-reference: adverb clauses of contrast (although, even though) are covered in full in Lesson 7 of the adverbs series.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
All three sentences express the same contrast. What is different about the grammar of each version? What punctuation marks are used differently? What comes after 'although' versus after 'however'?
'Although' is a subordinating conjunction — it introduces a dependent clause and joins it directly to the main clause within one sentence. 'However' is a connector (also called a conjunctive adverb or discourse marker) — it links two separate sentences or two independent clauses separated by a semicolon. The critical difference: 'although' can introduce a clause with only a comma; 'however' needs a full stop or semicolon before it and a comma after it. Writing 'She worked hard, however she failed' puts a comma where a full stop or semicolon is needed — a very common error.
The word 'while' is used in both sentences, but the meaning is different. What does 'while' mean in the first sentence? What does it mean in the second?
'While' can express contrast ('whereas' / 'although') or time ('at the same time as'). In the first sentence, 'while' means 'even though' or 'whereas' — it is a contrast conjunction. In the second, 'while' means 'during the time that' — it is a time conjunction. Context usually makes the meaning clear, but the ambiguity is real and worth teaching explicitly. When contrast is the intended meaning, 'whereas' or 'although' is often clearer. Note: this dual meaning of 'while' is also discussed in Lesson 7 of the adverbs series.
Look at what follows 'despite' in each version. What grammatical structure comes after 'despite'? Why is the third version wrong?
'Despite' is a preposition, not a conjunction — it must be followed by a noun phrase or a gerund phrase, not a full clause with a subject and finite verb. 'Despite the lack of textbooks' — noun phrase ✓. 'Despite there being no textbooks' — gerund phrase ✓. 'Despite there were no textbooks' — finite clause ✗. To use 'despite' before a full clause, the bridge phrase 'despite the fact that' is needed. This is one of the most consistent structural errors at intermediate level.
| Tense / Form | Use / Meaning | Example | Key time words |
|---|---|---|---|
| Word | Type | What follows it | Punctuation rule |
| although / even though | Conjunction | Subject + verb (dependent clause) | Comma after clause if clause comes first; no comma if main clause comes first |
| while / whereas | Conjunction | Subject + verb (dependent clause) | Same comma rule as 'although' |
| however / nevertheless | Connector | Complete new sentence | Full stop or semicolon before; comma after |
| despite | Preposition | Noun phrase or gerund phrase | 'Despite the fact that' needed before a full clause |
| on the other hand | Connector | Complete new sentence | More formal — use in written argument, not casual speech |
The conjunction / connector distinction is the most practically important concept in this lesson, and it is worth spending real time on it. A useful test for students: ask 'Could I put a full stop before this word?' If yes, it is a connector (however, nevertheless, on the other hand). If no — if the sentence would break apart — it is a conjunction (although, while, whereas). A second useful test: 'Can I move this word to different positions in the sentence?' Connectors like 'however' can appear at the start ('However, she failed'), in the middle ('She, however, failed'), or at the end ('She failed, however'). Conjunctions like 'although' are fixed at the start of their clause and cannot move around freely. These two tests together give students a practical toolkit for making the distinction without needing to understand the grammatical labels.
Quick checks: • Can a full stop go before this contrast word? → Connector (however, nevertheless) — use full stop or semicolon before it • Does the contrast word introduce a clause? → Conjunction (although, while, whereas) — comma after the clause if it comes first • Does 'despite' appear before a full clause? → Insert 'the fact that' to bridge it, or replace with 'although' • Do 'although' and 'but' both appear in the same sentence? → Conjunction collision — remove one
Choose the word that correctly completes each sentence. Think about whether the gap needs a conjunction or a connector.
Each sentence has one error with a contrast word. Find and correct it.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — Two families (5 min): Write two columns on the board: CONJUNCTIONS (although, while, whereas) and CONNECTORS (however, nevertheless, on the other hand). Ask students: what is the difference between these two groups in terms of how you use them in a sentence? Accept all answers, then introduce the key distinction: conjunctions join clauses inside a sentence; connectors link sentences.
STEP 2 — Punctuation: full stop or comma? (7 min): Write the same contrast expressed three ways (using 'although', 'however', and a full stop). Ask students to identify which punctuation mark belongs before each contrast word. Introduce the practical test: could a full stop go here? If yes, the word is a connector.
STEP 3 — Despite: preposition, not conjunction (5 min): Write three versions on the board — 'Despite the rain...', 'Despite working all night...', 'Despite she was tired...' Ask students which is wrong and why. Introduce the rule: 'despite' needs a noun or gerund. For a clause, use 'despite the fact that'.
STEP 4 — Collision check (8 min): Give students six sentences — half with conjunction collisions ('although...but', 'whereas...but') and half correct. Students identify errors and correct them. Remind students: this error was introduced in Lesson 2 of this series and appears frequently in student writing.
STEP 5 — Consolidate: rewrite with a different contrast word (5 min): Write three sentences on the board, each using a different contrast word. Ask students to rewrite each sentence using a different contrast word from a different family, making any necessary punctuation changes. This forces students to actively apply the conjunction/connector distinction.
