I'm confused to use "as" and "how", for instance

As you see below, this picture represents for me great emotional value


How you see below, this picture represents for me great emotional value

  • Always As.. you would only start a sentence with How if it's a question. Also your word order should be "this picture represents great emotional value for me" unless you put commas in: "this picture represents, for me, great emotional value". Commented Oct 30, 2015 at 12:46
  • Thanks man, about commas, I'm still learning how to use... Is it right? or Should I use "as"? Commented Oct 30, 2015 at 12:50

"How" is used often to make a question asking about the way something happen.

How does this watch work?

How can I go there?

And sometimes as a subordinated clause

I don't know how to go there

How is also used to ask about or acknowledge the amount/size or degree of something

How big is it?

How difficult it is to buy a ticket.

How can also be used to ask the opinions of others about something

How was the film.


"As" has many usages, it is generally used for making comparison especially when two things match

He is as old as you.

As a proposition "As" may be used to say what job, duty, appearance, role someone or something has

As a parent, you should protect your children

A flat stone was used as a table

also to say in the way that something happens or someone says

The money was repaid, as promised

Do as I say

It is also used to give reasons

As it was getting late, I turned around to start for home


Then remember, when you are using "How" you usually ask about or inform the way something happen but when you use "As", there are two concepts or things that match or correspond

  • I liked of example Do as I say. If I use "how", it'd give another meaning to the sentence, right? Commented Oct 30, 2015 at 23:17
  • @ThMoraes Yes then, it would probably mean speak in the way I speak or "speak like me", but using "as" means "do in the way I tell you"

In some languages both as and how are expressed by the same word. German comes to mind ("wie").

In order to distinguish between the two, you need to analyze what role the word has in the sentence:

If it is a question, use how:

How far is it?
How do you do?

Even if the question is rhetorical or basically an exclamation:

How nice of you!

If you need a conjunction, that is if you connect two phrases, sentences or clauses, use as:

As the sun rose (part 1), the day grew warmer (part 2).
As you can see in this diagram (part 1), sales increased substantially in 2011(part 2).
As he had already left (part 1), he didn't hear John's story (part 2).

Even more common is the correlative construction as ... as:

He's as tall as his mother now.
