Simple Sentences

A sentence may consist of just one main clause. A one-clause sentence is called a simple sentence and is very common in academic writing. It has a single subject and only one verb:

  • The scientists are working.

The addition of an object, adjectives, prepositional phases, adverbs or does not make it a complex sentence. Take this example of a simple sentence:

  • Leading scientists from the Particle Physics Research Group at the Univerisity of Bristol are currently working on upgrades to the Large Hadron Collider.

 The different parts of a simple sentence can be categorised into the following:

Subject + Verb + Object + Complement

S + V The economy has been improving.
S + V + O Smith and Khajawa (2003) offer an alternative approach.
S + V + C Structure and agency are interdependent
S + V + O + C Bourdieu criticised Coleman's definition of social capital as overly simplistic.
