Sentence structure is one of the first points you look at when you start to learn English. As soon as you can put two words together, you have a sentence. That’s all it takes – two words. A subject and a verb:

• I ran.
• She laughed.
• They fell.

While we may applaud children for these types of sentences, us grown-ups can’t really get away with this for long! 

Before we delve deeper into different sentence types, it will help to look at the meaning of certain terms first.

Sentence Structure Terms

Clause – part of a sentence made up by a SUBJECT and a VERB (as a minimum).

It can be an:

→ INDEPENDENT CLAUSE: makes sense on its own.

• Mary stayed late.

→ DEPENDENT CLAUSE: does not make sense on its own.

• Mary stayed late, because she needed to finish her report (‘because she needed to finish her report’ would not make sense on its own)

Conjunction – a word used to join clauses of a sentence:

→  CO-ORDINATING CLAUSE:

• most popular: and – but – or – nor – so – then – yet

→  SUBORDINATING CLAUSE:

• most popular: that – because – while – although – where – if

Different Sentence Types
