Question 1

What is the difference between like and as?

Accepted Answer

"Like" means "similar to" and is followed by a noun or pronoun — it shows a comparison: "She runs like the wind" (she runs in a way that is similar to the wind). "As" has two roles. First, as a preposition describing someone's function or position: "She works as a doctor" (she is actually a doctor — this is her real role). Second, as a conjunction meaning "in the way that" before a clause: "Do as I tell you." The key test: if you mean "similar to" but the person is not actually that thing, use "like." If you mean "in the role of" or "in the capacity of," use "as." "She sang like an angel" (comparison) versus "She performed as the lead singer" (actual role).

Question 2

Is "like I said" correct or should I use "as I said"?

Accepted Answer

In formal English and exams, "as I said" is correct because "as" introduces a clause (subject + verb): "As I said, the meeting starts at nine." "Like I said" is extremely common in everyday spoken English and informal writing, and many native speakers use it without thinking. However, in Cambridge exams, IELTS writing, and formal essays, "as" is the expected choice before a clause. Similar pairs include: "as I expected" (formal) versus "like I expected" (informal), and "as we discussed" (formal) versus "like we discussed" (informal). If you are preparing for an exam or writing formally, always choose "as" before a subject and verb.

Question 3

What does "such as" mean and when do I use it?

Accepted Answer

"Such as" introduces examples of a general category — it means "for example": "I enjoy team sports, such as football, basketball, and hockey." It is more formal than "like" for giving examples, though both are correct: "team sports like football" and "team sports such as football" mean the same thing. "Such as" is preferred in academic and formal writing because it sounds more precise. Do not confuse "such as" with "as" on its own: "such as" gives examples, while "as" describes roles or manner. Also note that "such as" is not followed by a complete list — it introduces a few representative examples. This expression appears frequently in B1 and B2 reading and writing texts.
