Vulnus in crure lente sanescit, quia puella matri paret et domi manet.

Because vulnus is in the nominative singular, so it is the subject of the verb sanescit.

• vulnus = wound
• sanescit = heals / is healing

So the basic core is:

• Vulnus ... sanescit = The wound heals / is healing

A learner might expect a person to be the subject, but here the wound itself is grammatically doing the healing.

Crure is the ablative singular of crus, cruris (leg).

After in, Latin uses:

• accusative for motion into something
• ablative for location in/on something

So:

• in crure = in the leg / on the leg depending on context

Since the wound is located there, Latin uses in + ablative.

Because in here means in/on in the sense of location, not motion.

Compare:

• in crus would not be right here
• in crure is correct because the wound is located in the leg

So the sentence is describing where the wound is, not movement toward the leg.

It can be understood as in the leg, and in natural English the translation may sometimes come out as on the leg, depending on the situation.

Latin often uses expressions a bit differently from English with body parts and locations. The important grammatical point is that in + ablative marks location. The exact English preposition may vary slightly in translation.

Lente is an adverb, meaning slowly.

It modifies sanescit:

• sanescit = heals
• lente sanescit = heals slowly

It is related to the adjective lentus, -a, -um, but here it is in adverb form.

Because sanescit means heals / is getting better / becomes healthy, while sanat usually means heals in the sense of heals something.

So:

• vulnus sanat would mean the wound heals something, which does not make sense here
• vulnus sanescit means the wound heals or the wound is healing

This is an important difference:

• sanare = to heal something
• sanescere = to heal, recover, become well

Because puella is the subject of both paret and manet.

• puella matri paret = the girl obeys her mother
• puella ... domi manet = the girl stays at home

Latin often uses one subject for two verbs without repeating it.

Because pareo (to obey) takes the dative, not the accusative.

So:

• matri = to/for the mother in form, but with paret it means obeys the mother

This is a very common thing learners need to remember: some Latin verbs take cases that do not match English expectations.

Examples:

• puella matri paret = the girl obeys her mother
• not matrem paret

Not in good English, but the Latin grammar works that way.

Since pareo takes the dative, you can think of it as is obedient to the mother if that helps you remember the construction. But the natural English translation is simply:

• matri paret = obeys her mother

So the dative is a grammar point, not something you should force into the English translation.

Quia means because and introduces a clause giving the reason.

So the sentence has:

• main clause: Vulnus in crure lente sanescit
• reason clause: quia puella matri paret et domi manet

Together:

• The wound heals slowly, because the girl obeys her mother and stays at home.

They are in the present indicative, just like sanescit.

This makes the whole sentence a straightforward present-time statement:

• the wound is healing slowly
• because the girl obeys her mother
• and stays at home

Latin often uses the present in simple factual narration like this.

Latin often does not need to say her when the meaning is clear from context.

So:

• puella matri paret literally says the girl obeys mother
• but in natural English we usually say the girl obeys her mother

Latin frequently leaves possessive words unstated when they are obvious.

Domi means at home. It is a special form called the locative.

Certain words, especially names of towns, small islands, and a few common nouns like domus, can use the locative to express place where.

So:

• domi = at home

This is why Latin does not need in domo here.

A learner should simply memorize domi as a very common expression.

Yes, in domo is possible Latin for in the house/home, but domi is the more idiomatic way to say at home.

There is a slight difference in feel:

• domi = at home
• in domo = in the house

In many contexts, domi is the natural choice.

It joins the two predicates that belong to puella:

• matri paret
• domi manet

So the girl does two things:

1. she obeys her mother
2. she stays at home

You can think of et as linking both the verbs and the ideas they express.

Because once the subject is established, Latin often does not repeat it unless there is a special need for emphasis or clarity.

So:

• quia puella matri paret et domi manet

naturally means:

• because the girl obeys her mother and stays at home

Repeating puella would be unnecessary here.

Latin word order is more flexible than English word order, because the endings show the grammatical relationships.

This sentence is quite natural:

• Vulnus in crure lente sanescit, quia puella matri paret et domi manet.

Some points a learner may notice:

• vulnus comes first, giving the topic immediately
• in crure stays near vulnus
• lente stands near sanescit
• matri comes before paret, which is very common with a dative object

The order helps the sentence flow, but the case endings are what really show who is doing what.

Look at both meaning and grammar:

• vulnus goes with sanescit because it is nominative singular
• in crure tells where the wound is
• lente modifies sanescit
• puella is the subject of paret and manet
• matri goes with paret because pareo takes the dative
• domi goes with manet because it tells where she stays

So the sentence breaks down neatly like this:

• Vulnus in crure lente sanescit
• quia puella matri paret et domi manet

That is often the best way to read a Latin sentence: find the verbs, then find their subjects and complements.
