As and like are prepositions or conjunctions. The prepositions as and like have different meanings.
| Like or As? | |
| As + noun means ‘in the role of’ . In this example, the speaker is the listener’s father. | As your father, I’ll help you as much as I can. |
Like + noun means ‘similar to’ or ‘in the same way as’. In this example, the speaker is not the father but wishes to act in a similar way to the father. | Like your father, I’ll help you as much as I can. |
We use like (but not as) to compare two things | She’s got a headache like me |
When we compare appearance or behaviour, we use like, not as | That house looks like a castle |
As is commonly used to talk about jobs | He worked for a long time as a teacher in Africa |
The conjunctions as and like have the same meaning when used in comparisons. Like is a little more informal. | Nobody understands him as I do. Nobody understands him like I do. |
