📘 One can walk out. One has to stay.
Your teacher has written two groups of words on the board: the blue butterfly and the butterfly landed. One is only a noun phrase; the other has a finite verb and can stand as a sentence, so length is not the test.
What you’ll learn
- Two labels on the boardUse a finite-verb test to tell a phrase from a clause, while recognising that it is a practical school test rather than the whole linguistic story.A phrase is organised around a head; a clause contains a verb. For everyday school examples, a finite verb is the quickest signal. Length does not decide.
- Phrases that do a jobName noun phrases and preposition phrases by their heads, and front an adverbial with a comma when it moves before the verb.The blue butterfly is a noun phrase. In the hall and after the storm are preposition phrases. After the storm, the boats came in. puts the adverbial first.
- The clause that can standRecognise a main (independent) clause as a complete thought, and join two of them with a coordinating conjunction rather than a comma splice.A main clause can stand as a sentence. FANBOYS join two standing clauses. A simple sentence has one independent clause; a compound sentence has two.
- The clause that leansMark a subordinate or relative clause, and repair a dependent-clause fragment by gluing it to a main clause or removing the hinge.Because, when, if, who, and that make a clause kneel. Year 5 relative clauses modify a noun. A leaning clause with a full stop is a shard, not a pot.
- Park it next to the right nounPlace a phrase or relative clause next to the noun it describes, and name the logical doer so a walking-phrase cannot dangle on the wrong subject.Walking down the path has to sit next to the walkers. Who lives next door has to sit next to the neighbour. A headline or a draft can be tested with the same four checks.
Questions this course answers
Which group of words is a clause?
The butterfly landed has a subject, the butterfly, and a finite verb, landed. The others have no finite verb, so they are phrases.
Match each group of words to its head.
A phrase is named after its head, while a clause contains a verb. In these school examples, the finite verb is the quickest signal that you have found a clause.
Put these checks in order when a group of words feels unfinished.
Membership first — is there a tensed verb and a subject? Then ask if the clause is independent. Only after that do you park leftover phrases.
Which sentence uses a fronted adverbial the way Year 4 teaches?
A fronted adverbial moves before the verb and is usually followed by a comma. After the storm, the boats came in. is the Year 4 pattern.
Name the kind of clause that has a subject and a verb but cannot stand as a sentence.
England’s glossary and Purdue both treat a subordinate (dependent) clause as a clause that cannot stand alone. A main clause can.
In which school year does England’s grammar appendix first ask pupils to use the terms clause and subordinate clause?
Year 3’s terminology for pupils introduces clause and subordinate clause. Year 2 already used subordination with when, if, that, because, but the word clause arrives in Year 3.
