Question

Guard from spelling mistake.' What is the common error in the above sentence?

Answer 1

Mistake is in singular form. It should be 'guard from spelling mistakes'

Answer 2

Answer :

This question is based on phrasal verbs.

Cambridge English Dictionary defines 'phrasal verb' as 'a combination of a verb and an adverb or a verb and a preposition, or both, in which the combination has a meaning different from the meaning of the words considered separately.'

Macmillan Dictionary defines phrasal verb 'guard against something' as 'to help to prevent something from happening.'

So, the correct sentence is :

Guard against spelling mistakes.
