Puer timidus ignem tangere non vult, quia se laedere timet.

Latin has no articles. That means it does not have separate words for the or a/an.

So puer can mean:

• the boy
• a boy
• simply boy

The exact sense comes from context. In a teaching sentence like this, English usually supplies the or a whichever sounds most natural.

Because timidus is an adjective agreeing with puer.

They match in:

• gender: masculine
• number: singular
• case: nominative

So timidus describes puer. Together they form the subject: the timid boy.

Ignem is the accusative singular of ignis, meaning fire.

It is accusative because it is the direct object of tangere:

• tangere = to touch
• the thing being touched = ignem

So:

• ignis = fire, as a dictionary form
• ignem = fire, as the object

Because Latin commonly uses a complementary infinitive after verbs like vult.

So:

• vult = he wants
• tangere = to touch

Together:

• tangere vult or vult tangere = he wants to touch

The infinitive tangere already includes the idea of English to touch. Latin does not need a separate word for to here.

Non usually goes before the word or idea it negates. Here it negates vult, so the sense is:

• non vult = does not want

Since vult is linked with tangere, the whole meaning becomes does not want to touch.

Latin word order is flexible, so you could also see:

• Puer timidus non vult ignem tangere

That means essentially the same thing.

Latin often leaves subject pronouns out because the verb ending already shows the person and number.

Here:

• vult = he wants
• timet = he fears

The ending -t tells you the subject is he/she/it in the singular. In this sentence, context shows it is the boy.

So Latin does not need to say he explicitly.

Quia means because. It introduces a clause giving the reason for the main statement.

So the sentence is structured like this:

• main idea: Puer timidus ignem tangere non vult
• reason: quia se laedere timet

In other words, the second part explains why the boy does not want to touch the fire.

Se is the reflexive pronoun, meaning himself, herself, or themselves, depending on context.

Here it refers back to the subject of its own clause, which is the boy:

• se laedere = to hurt himself

Latin uses se when the object refers back to the same subject.

If it referred to some other male person, Latin would use eum instead:

• se laedere = hurt himself
• eum laedere = hurt him

With verbs of fearing, Latin can use an infinitive to express the idea of being afraid to do something or being afraid of doing it.

So:

• se laedere timet = he fears hurting himself / he is afraid of hurting himself

This is a natural Latin construction.

You may also learn another fear construction later:

• timet ne se laedat

That means roughly the same thing, but it uses ne plus the subjunctive instead of an infinitive.

The word order is normal enough, but Latin is much freer than English.

This sentence puts the object and infinitive before the main verb:

• ignem tangere non vult

A more English-like order would be:

• non vult ignem tangere

Both are good Latin. The difference is mostly one of style or emphasis, not basic meaning.

Yes. The subject throughout is the boy, puer timidus.

So:

• puer timidus ... non vult = the timid boy does not want
• quia ... timet = because he fears

Since no new subject is introduced, Latin assumes the same one continues.
