On the other hand, ‘like’ is predominantly used as a preposition, implying similarity. For example:

  • She sings like an angel (similarity).
  • He acts like a child (comparison).

When to Use ‘As’ in English Sentences

‘As’ is used in several specific contexts:

  • To indicate a role or function: “He worked as a waiter before becoming a manager.”
  • To show a reason or cause: “As it was late, we postponed the meeting.”
  • To compare actions: “He runs as fast as his older brother.”

In comparisons, ensure the structure remains consistent. For instance: “As the queen commands, so shall we obey.”

When to Use ‘Like’ in English Sentences

‘Like’ is mainly used to draw comparisons:

  • Direct comparisons: “He looks like his father.”
  • Simile formation: “She sings like a nightingale.”
  • Descriptive analogy: “The car purrs like a kitten.”

‘Like’ often teams up with nouns and pronouns, becoming a crucial part of similes, a figure of speech commonly used in English literature.

Misconceptions and Common Errors

One common error is using ‘like’ in place of ‘as’ when joining clauses. For example, “Do it like I do” is incorrect when the intended meaning is “Do it as I do.” The latter joins two clauses, requiring ‘as.’

Conversely, saying “It looks as a bird” when intending to describe similarity is also incorrect. ‘Like’ should be used: “It looks like a bird.”

Practical Exercises for Mastery

To perfect your usage of ‘as’ and ‘like,’ practice by rewriting sentences correctly and creating your own sentences:

  • Incorrect: “He speaks English like an expert.” Correct: “He speaks English as an expert does.”
  • Provide your examples: Describe scenarios around you using ‘as’ and ‘like.’
