koko ni kuruma wo oite mo ii desu ka.

Yes, 置く（おく） basically means to put, to place, or to leave something somewhere.

With a car, Japanese often uses 置く in the sense of leave/park depending on context. So:

• 車を置く = to leave/park a car

In natural English, you would usually say park a car here, not put a car here, but the Japanese verb is broader.

A more specific verb for parking is:

• 駐車する（ちゅうしゃする） = to park

So ここに車を置いてもいいですか and ここに駐車してもいいですか can both be understood as asking if it is okay to park there, though 駐車する sounds more specifically about parking.

に marks the place where something is put, left, or exists in this sentence.

So:

• ここ = here
• ここに = here / in this place

Because 置く involves placing something at a location, に is the natural particle to mark that destination/location.

Compare:

• ここに車を置く = put/leave the car here

Because 車 is the direct object of 置く.

• を marks the thing being acted on.
• Here, the action is placing/leaving/parking
• The thing being placed is the car

So:

• 車を置く = to put/leave/park a car

If you used が, it would not fit this sentence pattern naturally, because 置く is acting on the car as an object.

This is a very common pattern:

• verb in て-form + もいいですか

It means:

• Is it okay to ...?
• May I ...?
• Would it be alright if I ...?

So here:

• 置く → 置いて (the て-form)
• 置いてもいいですか = Is it okay if I leave/park it?

Whole pattern:

• ここに車を置いてもいいですか
• Is it okay to park a car here?

In this pattern, も is part of the grammar ～てもいい, and you should learn it as a set expression.

So while も often means also, in ～てもいい it does not translate neatly as also. The whole pattern means:

• it is okay to do...
• you may do...

So it is better to think of:

• 置いてもいい = it is okay to leave/park it

rather than trying to translate each word separately.

It is asking for permission.

• ～てもいいですか = May I...? / Is it okay if I...?

It is not about ability, like Can I physically do this?

In English, can sometimes means either ability or permission, but in Japanese this pattern is clearly about permission.

So this sentence means something like:

• May I park the car here?
• Is it okay to leave the car here?

Japanese often leaves out the subject when it is obvious from context.

In English, we often say:

• Can I park my car here?

In Japanese, the I is usually unnecessary if the speaker is obviously talking about their own action.

So ここに車を置いてもいいですか naturally implies something like:

• May I leave/park a car here?
• May I park here?

The subject is understood from the situation.

Japanese nouns do not usually mark a/the the way English does, and they also often omit possessives if they are obvious.

So 車 could mean:

• a car
• the car
• my car

depending on context.

In a real situation, if you are asking about your own vehicle, the listener will usually understand it as my car even though my is not stated.

Yes. ですか makes it polite.

• 置いてもいいですか = polite
• 置いてもいい？ = casual

So:

• ここに車を置いてもいいですか = polite, normal, useful
• ここに車を置いてもいい？ = casual, used with friends or people you know well

A more formal version could be:

• ここに車を置いてもよろしいですか

That sounds more formal and respectful.

Yes. In normal Japanese writing, it would usually be written without spaces:

• ここに車を置いてもいいですか。

The spaces are often added only in learning materials to make it easier to read.

It can mean both, depending on context.

• In everyday English, if you are talking about a car and asking about a place, park is the most natural translation.
• But the Japanese 置く is broader and can also carry the idea of leave.

So depending on the situation, the sentence could feel like:

• May I park my car here?
• Is it okay to leave the car here?

For most learners, park a car here is the most natural way to understand it.

Yes, definitely.

• ここに車を置いてもいいですか = Is it okay to leave/park a car here?
• ここに駐車してもいいですか = Is it okay to park here?

駐車する is more specifically about parking vehicles, so it may sound a little more direct and exact in parking-related situations.

Both are natural, but 駐車する is especially useful when talking about parking lots, signs, or rules about parking.
