kono huku ha doro darake desu.

It is read:

この ふく は どろだらけ です。

In more natural writing, Japanese usually does not use spaces:

この服は泥だらけです。

Also, the particle は is pronounced wa here, not ha.

この means this when it directly modifies a noun.

• この服 = this clothing / these clothes
• これ = this one / this thing

So you can say:

• この服は泥だらけです。 = These clothes are covered in mud.
• これは泥だらけです。 = This is covered in mud.

Use この when a noun follows it. Use これ when it stands alone.

は marks the topic of the sentence.

So この服は means something like:

• As for these clothes...
• This clothing...

Then the rest of the sentence says something about that topic:

• 泥だらけです = is covered in mud / is full of mud

A very natural English translation is simply These clothes are covered in mud.

だらけ means full of, covered with, or littered with something.

It usually has a negative or undesirable feeling. For example:

• 泥だらけ = covered in mud
• ほこりだらけ = covered in dust
• 間違いだらけ = full of mistakes

So 泥だらけ gives the image that mud is all over the clothes.

Because だらけ attaches directly to a noun.

So:

• 泥 + だらけ → 泥だらけ
• ほこり + だらけ → ほこりだらけ
• 傷 + だらけ → 傷だらけ

You do not say 泥のだらけ here.

Think of だらけ as a set expression that combines with a noun to make a new descriptive expression.

For a learner, the easiest way to think about 泥だらけ is:

• it is a descriptive expression
• it can act as the predicate of a sentence with です or だ

So:

• この服は泥だらけです。 = polite
• この服は泥だらけだ。 = plain

It behaves somewhat like a noun-like or adjectival expression, but at your level it is most useful just to learn it as a pattern:

noun + だらけ

です makes the sentence polite.

Compare:

• この服は泥だらけです。 = polite
• この服は泥だらけだ。 = plain
• この服は泥だらけ。 = casual, often in conversation

So です does not add new meaning like is in a strict grammar sense; it mainly gives politeness and completes the sentence politely.

It can depend on context.

服 often works like clothes or clothing in a general sense, but it can also refer to a specific garment depending on the situation.

So this sentence could mean:

• These clothes are covered in mud
• This piece of clothing is covered in mud

Japanese often does not mark singular vs. plural as clearly as English does.

Usually, yes—or at least it usually suggests that there is too much of something.

For example:

• ごみだらけ = full of trash
• ミスだらけ = full of mistakes
• 血だらけ = covered in blood

Even when the noun itself is not inherently bad, だらけ often implies excess or messiness.

So 泥だらけ strongly suggests something unpleasant or undesirable.

Both can mean covered in mud, but the nuance is a little different.

• 泥だらけ = full of mud, mud all over it
• 泥まみれ = smeared/coated in mud, often emphasizing being literally covered

In many situations they are very similar. But:

• だらけ is broader and often means full of in a messy or undesirable way
• まみれ often gives a stronger physical image of something being smeared or coated

So この服は泥だらけです。 sounds very natural and common.

The spaces are there only to make it easier for learners to read.

Normally, Japanese would be written as:

この服は泥だらけです。

Japanese does not usually put spaces between words the way English does.
