Refresher no. 5 on the correct use of words

AS and LIKE used as prepositions do not express the same meaning.

AS expresses the role, function/capacity of a person or thing.
Consider the following examples:

  1. AS a mother, my friend attends to the basic needs of her children.
    In this sentence, my friend does a mother’s role. She is the mother.
  2. My neighbor earns much AS an electrician.
    Here, my neighbor’s role is that of an electrician. He is an electrician.
  3. Stop using your teeth AS a nail cutter.
    Here, the teeth function as a nail cutter.
  4. AS a resource person, the professor discusses the topic with authority.
    Here, the professor acts in his capacity as a resource person.
  5. Many go abroad AS tourists.
    LIKE, on the other hand, expresses comparison. It implies a resemblance or similarity between two persons, groups, or things. It means “similar to, “ “resembles,” “ in the same way,” “in the same manner.”
    Consider these examples:
  6. LIKE a mother, the teacher attends to the basic needs of her pupils in school.
    The teacher is not the mother of the pupils but she acts “ in a similar way.”
  7. My neighbor earns much LIKE a professional electrician.
    Here, my neighbor is not a professional electrician but his income is similar to that of a professional.

    Here, the house is similar to a stockroom.
  10. Some members of the choir sing LIKE angels.
    REMINDER: AS and LIKE used as prepositions are followed by a noun, a pronoun or a prepositional phrase, not by a subordinate clause.*
