√ The book depicts/portrays/describes/narrates the life on a woman who…

We don’t normally use explain + noun when we mean ‘tell’, ‘talk about’, ‘describe’, ‘portray’. When we use explain + noun, we normally mean ‘say what the reasons for something are’, or ‘make something clear or easy to understand’. For example:

  • Can you explain his strange behaviour? (=Can you say what the reasons for his strange behaviour are?)
  • The teacher explained the rules of the game.

We often use explain before question words such as how, who, why, etc.

  • He explained where the library is.
  • He explained how the machine works.
  • Please, could you explain why you are so late.
