Topic Explanation and Use
Core idea
Like and as look similar, but they do different grammar jobs.
Like and as can look similar, but they do different jobs. Like is usually followed by a noun phrase, while as is often followed by a clause or used to show a role.
Use like for similarity and as for function, role, or full clause patterns. This distinction matters because the wrong choice changes the grammar shape of the sentence.
At B2 level, build one correct base sentence first, then add detail without breaking grammar control.
Use it here
- Use like before a noun phrase.
- Use as before a clause or to describe a role.
- Check whether the next word group is a noun phrase or a full clause.
Watch it work

- Use like before a noun phrase.
- Use as before a clause or to show a role.
- Check the whole sentence again because like and as change the grammar shape.
- Choose the form that matches the meaning, not just the sound you prefer.
