Expressing Similarity and Difference: Like, As, Similar to, Different from

In English, we often need to compare things, people, or ideas to show how they are similar or different. This lesson will teach you how to express similarity and difference correctly and effectively.

1. Expressing Similarity

Using “Like”

Like is a preposition used before a noun or pronoun to show similarity. It means “similar to” or “in the same way as”.

• Ahmed is like his father. (they are similar)
• This flower smells like a rose.
• She sings like a professional singer.
• It looks like it will rain today.

Using “As”

As is a conjunction used before a clause (subject + verb) or as a preposition meaning “in the role of”.

• He works as a teacher. (in the role of a teacher)
• Do as I say, not as I do.
• She sings as her mother did when she was young.

Important distinction: Like vs As

• Like + noun/pronoun: “He runs like a cheetah.” (comparing to a cheetah)
• As + subject + verb: “He runs as a cheetah does.” (comparing actions)

Using “Similar to” and “The same as”
