wǒ tǎoyàn xiàyǔ.

Mandarin usually follows Subject + Verb + Object order, just like basic English.

• 我 = I
• 讨厌 = hate / dislike
• 下雨 = to rain / raining

So 我讨厌下雨 literally follows:

• I + hate + raining

That is why 下雨 comes after 讨厌: it is the thing being hated.

In this sentence, 下雨 is best understood as a verb phrase meaning to rain or raining.

• 下 originally means to fall
• 雨 means rain

Together, 下雨 means rain falls → it rains / to rain

So in 我讨厌下雨, the speaker is saying they hate rainy weather or when it rains, not just the noun rain in an abstract sense.

Because Mandarin does not need a dummy subject like English it.

In English, we say:

• It is raining
• It is cold

But the it does not refer to anything real. It is just required by English grammar.

In Mandarin, you can simply say:

• 下雨了 = It’s raining / It rained
• 很冷 = It’s cold

So 下雨 works fine by itself without any subject.

It can mean either of these in natural English:

• I hate rain
• I hate rainy weather
• I hate it when it rains

Mandarin often leaves this slightly broad. The sentence naturally covers the general idea of disliking rainy conditions or the event of rain.

If you wanted to be more explicit, you could also say:

• 我讨厌下雨天。 = I hate rainy days.
• 我讨厌下雨的时候。 = I hate when it rains.

But 我讨厌下雨 is already completely natural.

Yes. Both are correct, but the strength is different.

• 我不喜欢下雨 = I don’t like rain / I don’t like it when it rains
• 我讨厌下雨 = I hate rain / I hate it when it rains

讨厌 is much stronger than 不喜欢.

So if you just mildly dislike rainy weather, 不喜欢 may sound more natural. If you really cannot stand it, 讨厌 fits well.

Yes. 讨厌 can be used for both.

Examples:

• 我讨厌下雨。 = I hate rain.
• 我讨厌他。 = I hate him / I find him annoying.

However, when used about a person, the tone can be quite strong. In some contexts, 讨厌 can also mean annoying:

• 他很讨厌。 = He is annoying.

So learners should pay attention to context.

Because 下雨 is acting as the object of the verb 讨厌, and Mandarin often allows verbs or verb phrases to be objects directly.

So the structure is simply:

• 我 = subject
• 讨厌 = main verb
• 下雨 = object (an action/event)

Mandarin does this quite naturally. English also does something similar:

• I like swimming
• I hate waiting

Here, swimming and waiting are actions functioning as objects. Mandarin works similarly.

讨厌 is pronounced tǎoyàn.

Tone by tone:

• 讨 = third tone (tǎo)
• 厌 = fourth tone (yàn)

A rough pronunciation guide:

• tǎo sounds a bit like tao with a dipping tone
• yàn sounds like yen or yan with a sharp falling tone

So:

• 讨厌 = tǎo-yàn

Be careful not to flatten the tones too much, because tones help distinguish words in Mandarin.

The normal expression is 下雨, not 雨下.

Mandarin commonly uses 下 + weather noun for things that fall from the sky:

• 下雨 = to rain
• 下雪 = to snow

So 下雨 is the fixed and natural form.

Yes, you can.

• 我讨厌下雨。 = I hate rain.
• 我很讨厌下雨。 = I really hate rain.

Here 很 adds emphasis, making the dislike feel stronger or more explicit.

But even without 很, 讨厌 is already strong, so the original sentence sounds complete and natural.

Yes, but it is a little different in feeling.

• 我讨厌雨。 = I hate rain.
• 我讨厌下雨。 = I hate it when it rains / I hate rainy weather.

雨 is the noun rain.
下雨 is the event or action raining.

In everyday speech, 我讨厌下雨 often sounds more natural because people usually mean they dislike the weather situation, not the abstract noun by itself.
