Sentence structure

Recommendations

Avoid complex sentence structures. They are less easy to understand quickly understanding them requires more cognitive effort than simple sentences.

Complexity is defined by:

  • the number of clauses in a sentence, the more clauses the more complex it is
  • word order – how easy or difficult it is for the brain to parse a phrase, that is to recognise, group and take meaning from words that together convey meaning

Word order example:

a) "The red fox jumped over the gate."
b) "The fox, which was red, over the gate jumped."

Sentence a) is easier to understand than sentence b). Both are grammatically correct.
