조금 means a little or a small amount.
The particle 만 means only or just.

So 조금만 means just a little or only a small amount.

In this sentence, 만 adds the nuance that the speaker wants the amount to be limited. It is not just some dressing, but specifically just a little dressing.

For example:

• 조금 넣어 주세요 = Please add a little
• 조금만 넣어 주세요 = Please add just a little

The second one sounds more precise and often more natural when making a request about quantity.

The particle -를 marks the direct object of the verb.
Here, the verb is 넣다, which means to put in, to add, or to insert.

So 소스를 넣다 means to add the sauce.

Breaking it down:

• 샐러드 소스 = salad dressing / salad sauce
• 샐러드 소스를 = the salad dressing, as the thing being added

English does not usually mark objects with a special particle, so this can feel new to English speakers. In Korean, the object marker helps show what the action is being done to.

넣어 주세요 is a very common and polite way to ask someone to do something for you. It literally has the sense of please do X.

• 넣다 = to put in / add
• 넣어 주세요 = please add it

By contrast, 넣으세요 can also be polite, but it often sounds more like an instruction, direction, or command depending on context.

So:

• 넣어 주세요 = Please add some
• 넣으세요 = Add some / Please add some

In service situations, such as talking to restaurant staff, -아/어 주세요 is often a very natural choice because it sounds like a polite request rather than a direct instruction.

This is because Korean verbs change form when they are conjugated.

The dictionary form is 넣다.
To make the -아/어 주세요 form, you remove -다 and add -어 주세요.

So:

• 넣다
• stem: 넣-
• 넣어 주세요

This happens because 넣다 is an 어-type verb in this form.

You do not need to think of it as irregular here. It is just the normal conjugated form used before 주세요.

It is written as two words here: 샐러드 소스.

This is a noun + noun combination:

• 샐러드 = salad
• 소스 = sauce

Together, 샐러드 소스 usually means salad dressing.

Korean often uses noun combinations like this without adding extra words such as of or for. So literally it is something like salad sauce, but in natural English it usually means salad dressing.

Korean word order is more flexible than English, but the most neutral order here is:

• object: 샐러드 소스를
• amount adverb: 조금만
• verb: 넣어 주세요

So the sentence structure is basically:

[salad dressing] [just a little] [please add]

The verb usually comes at the end in Korean. That is one of the biggest differences from English.

You may also hear slightly different word orders in conversation, but this version sounds very natural and standard.

Yes, you often can.

In everyday spoken Korean, object particles like -을/-를 are frequently omitted when the meaning is clear.

So both of these are natural:

• 샐러드 소스를 조금만 넣어 주세요
• 샐러드 소스 조금만 넣어 주세요

The version with -를 is a little more explicit and grammatically complete.
The version without it is very common in speech.

For learners, it is good to recognize both, but using the particle is perfectly safe and correct.

주세요 is polite and commonly used in everyday situations.

It is appropriate for:

• restaurants
• shops
• talking to someone you do not know well
• polite requests in daily life

It is less formal than very formal styles like 주십시오, but more polite than casual forms used with friends.

For example:

• casual: 넣어 줘
• polite: 넣어 주세요
• very formal: 넣어 주십시오

So in a restaurant or café, 넣어 주세요 sounds natural and polite.

In this sentence, 넣다 is best understood as to add.

The core meaning of 넣다 is to put in or to place inside, but in food-related contexts it often works like add in English.

For example:

• 소금을 넣다 = add salt
• 설탕을 넣다 = add sugar
• 소스를 넣다 = add sauce

So even though the literal sense is put in, the natural English translation here is often Please add just a little salad dressing.

Yes. 조금만 often sounds soft, practical, and natural.

Instead of specifying an exact amount, it politely communicates:

• not too much
• just a small amount
• please keep it light

This is especially common in food orders and requests.

For example:

• 물 조금만 주세요 = Please give me just a little water
• 밥 조금만 주세요 = Please give me just a little rice

So in this sentence, 조금만 helps the request sound gentle and natural.

A more casual version would be:

• 샐러드 소스를 조금만 넣어 줘

This uses 줘, the casual form of 주세요.

If you are speaking to a friend or someone much younger, this can be fine. But in a restaurant or to someone you should be polite to, 넣어 주세요 is the better choice.

So:

• 넣어 줘 = casual
• 넣어 주세요 = polite
• 넣어 주십시오 = very formal

For most learners, 넣어 주세요 is the safest and most useful form in everyday public situations.
