Lo smash dell'avversario esce, perciò può iniziare il gioco all'esterno.

Because smash begins with s + consonant (sm-), and masculine singular nouns with that sound usually take lo in Italian:

• lo smash
• lo sport
• lo studente

So here lo smash is the correct definite form.

dell' is the contraction of di + l'.

The noun is l'avversario (the opponent), so:

• lo smash dell'avversario = the opponent's smash

Italian often expresses possession with di rather than using an apostrophe like English 's.

Compare:

• la racchetta del giocatore = the player's racket
• lo smash dell'avversario = the opponent's smash

Yes. Esce is from uscire = to go out / to come out / to exit.

In a sports context, la palla esce or il colpo esce means the shot goes out of bounds. So here lo smash dell'avversario esce means the opponent's smash goes out.

This is very natural sports language in Italian.

Perciò means therefore, so, or for that reason.

It links the two parts of the sentence:

• Lo smash dell'avversario esce = the opponent's smash goes out
• perciò = therefore / so
• può iniziare il gioco all'esterno = he/she can begin play outside

Other similar connectors are:

• quindi = so, therefore
• per questo = because of this, for this reason

Perciò is a bit more formal or written than plain spoken quindi, but both are common.

Italian often leaves the subject pronoun unstated when it is understood from context.

Può iniziare literally means can begin or is allowed to begin. The sentence does not explicitly say he/she or the player, but the subject is understood from the situation.

Depending on the context, it could mean:

• the player can begin play outside
• he/she can begin play outside

In sports instructions, Italian often omits the subject when it is obvious.

Because Italian usually does not need subject pronouns unless they are needed for emphasis, contrast, or clarity.

So Italian prefers:

• può iniziare

rather than:

• lui può iniziare
• lei può iniziare

You would add lui or lei only if you want to stress who is allowed to do it.

Yes. Iniziare and cominciare can both mean to begin / to start.

So both are possible in many contexts:

• iniziare il gioco
• cominciare il gioco

Iniziare can sound slightly more formal or technical, while cominciare is very common in everyday speech. In a rule or explanation about sport, iniziare sounds perfectly natural.

All'esterno means outside or on the outside.

It is formed from:

• a
  • l'esterno → all'esterno

So the apostrophe appears because esterno here is preceded by l'.

In a sports context, all'esterno usually means outside the court / outside the playing area, depending on the sport and the rule being described.

Because esterno here is used as l'esterno, and the preposition combines with the article:

• a + l' = all'

So:

• all'esterno = to/on the outside

This is the same pattern as:

• all'ingresso
• all'uscita
• all'inizio

Sometimes yes, but the meaning and tone are a little different.

• fuori = out / outside
• all'esterno = on the outside / outside, often more formal or technical

In sports language, all'esterno can sound more precise, especially if it refers to play happening outside the court boundaries in a rule-based way. Fuori is often more general and colloquial.

For example:

• La palla va fuori = The ball goes out
• Giocare all'esterno = To play outside the court area

So all'esterno fits well in a technical sports explanation.

Italian often uses the present tense to describe:

• rules
• instructions
• sports commentary
• general situations

So:

• esce
• può iniziare

are in the present because the sentence is describing what happens in that situation as a rule or typical event.

English often does the same:

• If the opponent's smash goes out, the player can start play outside.

It is a borrowed word from English, but it is commonly used in Italian sports language, especially in racket sports.

Italian often keeps English sports terms, for example:

• smash
• match
• tennis
• sport

Even though the word comes from English, it still follows Italian grammar when articles are used:

• lo smash
• gli smash

The plural is gli smash.

So:

• singular: lo smash
• plural: gli smash

Even though smash does not change form, the article changes:

• lo smash dell'avversario
• gli smash dell'avversario

This is common with many borrowed words in Italian.
