I think the main difference between like and as is in formality. Like is common in conversation in comparative metaphors; as is still used in conversation, but it’s more frequent in written English. I don’t think I can think of examples as romantic as yours Silvio, but I’ll try! Here we go:
The view was just as I remembered it.
In conversation, we might say, The view was just like I remembered it.
Exercise is just as important as diet for good health.
In conversation, we might say: Exercise, just like diet, is important for good health.
But I think we’d use the as ... as structure to say something like She’s as lovely as her sister.
In all of these examples, two states or things are being compared: the view before and now; exercise and diet; two sisters. We can see that as is being used as a preposition to show comparison, and like is the informal equivalent.
And, to continue with like: as well as being a verb that we’re all familiar with (as in I do like you, Silvio), like has a couple of different meanings you may not be aware of. We can use like to give examples, where it means such as. Here we go:
Some consumer goods, like household electrical products, are cheaper to purchase than repair.
Many successful Broadway shows, like Chicago, Annie and Fame, have been turned into films.
We were looking for a good present for a five-year-old, like a bicycle or a remote controlled toy.
And finally Silvio, I’d like to tell you about another use of like, which is as a kind of filler or a speech marker. Listen to these examples, which are taken from conversation:
My brother is like really, really good on the electric guitar.
I’ve just got to get, like, one hundred more points to move onto the next level.
This kind of usage is very common in the speech of young people, like my son. And I’m going to end my explanation here – thank you for your question and I hope this has helped, Silvio!
