朝は marks morning as the topic: as for the morning / in the morning.

In Japanese, time words like 朝, 今日, 昨日, 明日 often do not need a particle at all, and when you use は, it gives a contrastive or topic-setting feeling.

So 朝はまだ晴れていなかった feels like:

As for the morning, it still wasn’t clear/sunny yet.

If you used 朝に, it would sound less natural here. に is more common with more specific points in time, like 7時に.

With a negative verb, まだ usually means still not or not yet.

So:

まだ晴れていなかった
= it was still not sunny / it had not cleared up yet

This is a very common pattern:

• まだ来ていない = hasn’t come yet
• まだ食べていない = haven’t eaten yet

So here, まだ shows that by morning, the weather had not improved yet.

This is a very common learner question.

晴れる means to clear up / become sunny.
The form 晴れている describes the state of the weather being clear/sunny.

So:

• 晴れなかった = it didn’t become sunny / it didn’t clear up
• 晴れていなかった = it was not in a clear/sunny state

In weather expressions, ～ている is often used for the current condition:

• 晴れている = it is sunny
• 曇っている = it is cloudy
• 雨が降っている = it is raining

So まだ晴れていなかった is natural because it describes the weather condition at that time.

ので means because / since.

In this sentence:

朝はまだ晴れていなかったので、ゆっくり歩いた。
= Because it still hadn’t cleared up in the morning, I walked slowly.

Compared with から, ので often sounds:

• a little softer
• a little more explanatory
• slightly more formal or neutral

Very roughly:

• から = more direct, more personal
• ので = more explanatory, a bit gentler

Both could work here, but ので fits well because the speaker is calmly giving the reason.

Yes, ぬれた is the past form of ぬれる (to get wet), but when it comes before a noun, it often describes a resulting state.

So:

ぬれた道
literally = a road that got wet
natural English = a wet road

Japanese often uses a past form before a noun this way:

• 割れたガラス = broken glass
• 閉まったドア = a closed door
• ぬれた服 = wet clothes

So even though it looks like past tense, in English it is often best understood as an adjective-like description.

Here, で marks the place where slipping might happen.

So:

ぬれた道で滑らないように
= so as not to slip on the wet road

The verb 滑る often uses で for the place where the slipping happens.

By contrast, を with 道 would more naturally go with 歩く:

• 道を歩く = walk along the road

In this sentence, 道で belongs with 滑らない, not with 歩いた.

Verb (plain form) + ように often means:

• so that...
• in order to...
• so as to...

With a negative verb, it means so as not to...

So:

滑らないように
= so as not to slip

The full idea is:

ぬれた道で滑らないようにゆっくり歩いた。
= I walked slowly so as not to slip on the wet road.

This pattern is extremely common:

• 忘れないようにメモした。 = I wrote it down so I wouldn’t forget.
• 風邪をひかないように気をつける。 = I take care not to catch a cold.

Both can express purpose, but they are not always interchangeable.

ように is often used when the goal is something the speaker tries to make happen or avoid, especially when it is not totally under direct control.

滑らないように sounds natural because not slipping is something you aim for, but you cannot control it 100%.

By contrast, ために is more common when the action is a more direct, intentional purpose:

• 日本へ行くためにお金をためている。
  = I’m saving money in order to go to Japan.

So here, 滑らないように is the more natural choice.

ゆっくり is an adverb meaning slowly.

It modifies 歩いた:

ゆっくり歩いた
= walked slowly

This tells you how the person walked.

Common similar adverbs are:

• 早く歩く = walk quickly
• 静かに話す = speak quietly
• 丁寧に書く = write carefully

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

In this sentence, 歩いた strongly suggests the speaker or a known person, so English naturally supplies I:

I walked slowly...

Also, the weather clause does not explicitly say the sky or the weather either. Japanese often omits those when they are obvious:

朝はまだ晴れていなかった
= It still wasn’t sunny / it hadn’t cleared up yet in the morning

So omitted subjects are very normal in Japanese.

A helpful way to break it up is:

朝は
= as for the morning

まだ晴れていなかったので、
= because it still hadn’t cleared up yet,

ぬれた道で
= on the wet road

滑らないように
= so as not to slip

ゆっくり歩いた。
= I walked slowly.

So the whole sentence is built like this:

[time/topic] + [reason] + [place] + [purpose/precaution] + [main action]

That is a very common Japanese sentence pattern.
