Here 길 means the way / the route / the road in the sense of directions.

It takes 을 because it is the object of 모르다 in this expression: 길을 모르다 = to not know the way / to not know the route.

So:

• 길을 모르다 = not know the way
• 길이 would mark 길 as the subject, which is not what this sentence is doing

This is a very common Korean pattern:

• 이름을 모르다 = not know a name
• 방법을 모르다 = not know a method
• 길을 모르다 = not know the way

잘 모르겠으면 can be broken down like this:

• 잘 = well, clearly
• 모르겠다 = to not know / to not be sure / to not be able to tell
• -으면 = if

So literally it is something like:

• if you don’t know well
• more naturally: if you’re not sure
• in this sentence: if you’re not sure about the way

A key point is that 잘 with a negative verb often means properly / clearly / confidently, not just well in the English sense.

So 길을 잘 모르다 means:

• to not know the way well
• to be unclear about the route
• to be unsure where to go

Yes, 잘 often means well, but in Korean it is also commonly used with negative verbs to mean properly, clearly, or really.

So:

• 잘 알아요 = I know it well
• 잘 몰라요 = I don’t really know / I’m not very familiar with it

In this sentence, 길을 잘 모르겠으면 does not mean something awkward like if you don’t know the road skillfully. It means:

• if you don’t know the way very well
• if you’re not familiar with the route
• if you’re unsure of the directions

This is a very natural Korean usage.

This is a great question because the difference is subtle but important.

• 모르면 = if you don’t know
• 모르겠으면 = if you don’t know / if you’re not sure / if you can’t tell

모르겠다 often sounds a little softer and more subjective. It can suggest:

• uncertainty
• inability to decide
• not being sure at the moment

So:

• 길을 모르면 = if you don’t know the way
• 길을 모르겠으면 = if you’re not sure about the way / if you can’t really tell where to go

In everyday speech, 모르겠으면 can sound slightly more natural when talking about uncertainty in a situation.

-으면 / -면 is the conditional ending meaning if.

Which form you use depends on whether the verb stem ends in a consonant or vowel:

• vowel stem + -면
• consonant stem + -으면

Here the form comes from 모르겠다.

1. Remove 다 → 모르겠
2. The stem ends in a consonant sound
3. Add -으면 → 모르겠으면

So 모르겠으면 means if (you) are not sure / if (you) don’t know.

It means look at the signs first.

Breakdown:

• 표지판 = sign, signboard, road sign
• 을 = object marker
• 먼저 = first
• 보고 = look at, and then...

Here 보다 means to look at / check / consult.
And -고 links actions in sequence:

• 표지판을 먼저 보고 = look at the sign(s) first, and then...

So the sentence is telling the listener to check the signs before continuing.

Because Korean often connects actions in order using -고.

Here the structure is:

• 표지판을 먼저 보고 = look at the signs first
• 걸어가 = walk / keep going

Together:

• Look at the signs first and then go on walking
• Check the signs first before you continue walking

The -고 here is basically and then.

So the sentence is not awkwardly saying two unrelated things. It is giving a sequence of actions:

1. check the signs
2. continue walking

걸어가다 = to go by walking or to walk and go

Breakdown:

• 걷다 = to walk
• 가다 = to go
• combined as 걸어가다 = to go on foot / walk along / walk away

Compared with 가다, 걸어가다 makes the method more explicit: the person is moving by walking.

So:

• 가 = go
• 걸어가 = walk on / go walking / continue on foot

In this sentence, 걸어가 fits well because the context is following a route.

가다 usually implies movement away from the speaker or simply in a direction onward.

So 걸어가 often feels like:

• walk on
• keep walking
• walk that way

If the motion were toward the speaker, Korean might use 걸어오다 instead:

• 걸어가다 = walk away / walk onward
• 걸어오다 = walk toward here

In this sentence, the speaker is telling someone how to proceed along a route, so 걸어가 is very natural.

Yes. In this sentence, 걸어가 is an informal command in casual speech.

The full plain verb is 걸어가다, and here it appears in a casual sentence-final form directed at someone close in age or lower in status, or in a very informal context.

Possible style versions:

• 걸어가. = casual
• 걸어가세요. = polite
• 걸어가라. = direct/blunt command

So the whole sentence has a casual, conversational tone.

Because Korean often omits subjects when they are obvious from context.

In English, we usually need to say:

• If you don’t know the way, look at the signs first and keep walking.

In Korean, the you is understood, so it is left out:

• 길을 잘 모르겠으면 표지판을 먼저 보고 걸어가.

This is extremely normal. Korean frequently drops:

• subject
• object
• topic

if the listener can already understand them from context.

It can be understood as either a sign or signs, depending on context.

Korean nouns do not always mark singular/plural the way English does. So:

• 표지판을 보고 could mean look at the sign
• or look at the signs

If the speaker wanted to strongly emphasize plural, they might say 표지판들, but that is often unnecessary.

So in natural English translation, both are possible depending on the situation:

• look at the sign first
• look at the signs first

Yes. Even though 걸어가 is grammatically a command, in context the whole sentence can sound like practical advice:

• If you’re not sure of the way, check the signs first and then keep going.

Korean commands are often used for everyday guidance, suggestions, or instructions, not only harsh orders.

The tone depends on:

• who is speaking to whom
• voice and context
• relationship between speaker and listener

So this sentence can feel like friendly advice such as:

• If you’re unsure, just look at the signs first and keep walking.

Yes, definitely.

In many situations, 보다 is broader than just physically looking. It can mean:

• look at
• check
• examine
• consult

So 표지판을 먼저 보고 can naturally be understood as:

• look at the signs first
• check the signs first
• consult the signs first

In English, check the signs first may actually sound more natural in this situation than a literal look at the signs first.
