In Japanese, が often marks the thing that is experiencing a condition or state.

In のどが痛い, the throat is the thing that hurts, so のど takes が.

This is a very common pattern with body parts and feelings:

• 頭が痛い = My head hurts.
• お腹が痛い = My stomach hurts.
• 目が痛い = My eyes hurt.

Even though English says I have a sore throat or my throat hurts, Japanese often structures it more like the throat is painful.

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

So instead of saying:

• 私はのどが痛いので、温かいお茶を飲みます。

it is very natural to simply say:

• のどが痛いので、温かいお茶を飲みます。

The listener usually understands that the speaker is talking about themself.

痛い is an i-adjective, and i-adjectives can end a sentence by themselves.

So:

• のどが痛い。 = My throat hurts.

is already complete.

You do not say 痛です.

If you want to make it polite, you say:

• のどが痛いです。

Here, です is added after the full i-adjective 痛い.
So the correct polite form is 痛いです, not 痛です.

ので means because or since. It gives the reason for the action in the second part of the sentence.

So the structure is:

• のどが痛いので = because my throat hurts
• 温かいお茶を飲みます = I drink warm tea

Compared with から, ので often sounds a little softer, more explanatory, and slightly more formal.

For example:

• のどが痛いから、温かいお茶を飲みます。
• のどが痛いので、温かいお茶を飲みます。

Both are correct, but ので can sound a bit gentler.

The comma is there to make the sentence easier to read. It marks a natural pause between the reason and the main action.

• のどが痛いので、 = because my throat hurts,
• 温かいお茶を飲みます。 = I drink warm tea.

In Japanese, commas are often used more flexibly than in English. This comma is natural, but depending on style, you may also see similar sentences written without one.

Japanese has a few words that can mean warm, and the kanji used can hint at the kind of warmth.

• 温かい is often used for things that are warm to the touch or in a general, gentle sense, including drinks and food.
• 暖かい is more often used for weather, air, rooms, clothing, and overall environmental warmth.

So for tea, 温かいお茶 is very natural.

The お in お茶 is an honorific/polite prefix. It makes the word sound more natural and polite.

With some words, this prefix is optional, but with お茶, it is extremely common. In daily speech, お茶 sounds much more natural than just 茶.

This お does not change the basic meaning. It simply adds politeness or softness.

を marks the direct object of the verb, meaning the thing being acted on.

Here, the verb is 飲みます = drink, so the thing being drunk is:

• 温かいお茶を = warm tea

This is a basic Japanese pattern:

• 水を飲みます = drink water
• ご飯を食べます = eat rice / a meal
• 本を読みます = read a book

Japanese normally puts the main verb at the end of the clause or sentence.

So the sentence builds up like this:

• reason: のどが痛いので
• object: 温かいお茶を
• verb: 飲みます

This is normal Japanese word order. English speakers often want the verb earlier, but in Japanese it usually comes last.

飲みます is the polite -ます form of 飲む.

So:

• 飲む = plain form
• 飲みます = polite form

Because the sentence uses polite style, it ends with 飲みます.

You should also notice that the sentence mixes naturally with ので and polite speech:

• のどが痛いので、温かいお茶を飲みます。

If you wanted a plain-style version, you could say:

• のどが痛いので、温かいお茶を飲む。

With i-adjectives, you can attach ので directly to the plain form:

• 痛い
  • ので → 痛いので

That is the normal pattern.

Similarly:

• 寒いので = because it’s cold
• 眠いので = because I’m sleepy
• 高いので = because it’s expensive

You do not need to turn 痛い into a noun or use any extra word before ので.

Yes. You could say:

• のどが痛いから、温かいお茶を飲みます。

This also means Because my throat hurts, I drink warm tea.

The difference is mostly nuance:

• から: common, direct, casual-to-neutral
• ので: a bit softer, more explanatory, often slightly more formal

Both are correct, but learners should know that ので often sounds less blunt.

Yes, very often.

The word can be written as:

• のど
• 喉
• sometimes 喉 in more formal or written contexts

In everyday Japanese, body-part words are often written in hiragana, especially when that is easier to read. So のどが痛い in hiragana looks completely natural.
