Mi spiace per il telefono.

Mi means to me.

Italian uses the verb spiacere a bit like piacere. Literally, mi spiace is something like it is regrettable to me or it causes me regret.

So:

• mi = to me
• spiace = is sorry / is regrettable

That is why Italian does not say this in the same structure as English I am sorry.

Because spiacere does not work like a normal I + verb structure here.

In English, you say I am sorry.
In Italian, the idea is closer to:

• Mi spiace = It is sorry/regrettable to me

So the verb is in the third person singular:

• spiace

There is an implied subject, something like it or this situation.

Compare:

• Mi piace = I like it
• Mi spiace = I’m sorry / I regret it

In both cases, mi is the person affected, and the verb stays in the third person singular.

Yes, in everyday use they usually mean the same thing: I’m sorry.

However:

• Mi dispiace is often felt to be a little more standard or neutral.
• Mi spiace can sound slightly shorter, more conversational, or more immediate.

So all of these can work, depending on context:

• Mi spiace per il telefono.
• Mi dispiace per il telefono.

Both are natural.

Here per means about or for, depending on how you translate it naturally in English.

So:

• Mi spiace per il telefono = I’m sorry about the phone

In Italian, per is very common after mi spiace / mi dispiace when you say what you are sorry about:

• Mi spiace per il ritardo = I’m sorry about the delay
• Mi dispiace per la tua perdita = I’m sorry for your loss

Because Italian uses the definite article much more often than English.

So where English often says:

• about the phone or even just
• about your phone / about phone stuff in context,

Italian commonly says:

• per il telefono

The article il is normal here. Italian generally prefers an article before a singular countable noun unless there is a specific reason to omit it.

It can mean either, but in modern everyday English the best translation is usually the phone.

Italian telefono covers the normal meaning of phone/telephone.
In most real situations, a learner should understand:

• il telefono = the phone

It can do either, depending on context.

Mi spiace is broad. It can mean:

• I’m sorry because I caused something
• I’m sorry because something bad happened to you

So Mi spiace per il telefono could mean:

• I’m sorry about the phone because I broke it / damaged it / caused a problem or
• I’m sorry about the phone because something happened to your phone and I feel bad for you

The sentence itself does not force only one interpretation. Context tells you which one is meant.

Usually, per il telefono is the more natural choice for I’m sorry about the phone.

Using di or del after mi spiace / mi dispiace can happen in some structures, but for a straightforward sorry about X, learners should strongly prefer:

• Mi spiace per il telefono
• Mi dispiace per il telefono

So if your goal is to sound natural and safe, use per here.

Yes, but it changes the tone.

• Mi spiace per il telefono = I’m sorry about the phone
• Spiace per il telefono = more like It’s unfortunate about the phone or a more impersonal sorry about the phone

Without mi, it sounds more detached or impersonal.
With mi, it clearly shows my regret or my sympathy.

For most personal conversation, mi spiace is the more normal choice.

The standard order is:

• Mi spiace per il telefono.

That is the most neutral and natural version.

Italian can move things around for emphasis, for example:

• Per il telefono, mi spiace.

But that sounds more marked or stylistic. A learner should use:

• Mi spiace per il telefono.

It is pronounced approximately SPYAH-cheh.

More exactly:

• spia sounds like spya
• ce sounds like che in check, but shorter and cleaner

So:

• spiace ≈ SPYAH-cheh

The stress is on the first syllable:

• SPIA-ce

Yes, but it is slightly conversational.

In many situations, Mi spiace per il telefono is perfectly fine and polite.

If you want to sound a little more formal or careful, you could say:

• Mi dispiace per il telefono.

That version is often preferred in more formal or polished speech, but mi spiace is still very common and acceptable in everyday Italian.

A very useful pattern is:

• Mi spiace per + noun
• Mi dispiace per + noun

Examples:

• Mi spiace per il ritardo. = I’m sorry about the delay.
• Mi spiace per il problema. = I’m sorry about the problem.
• Mi dispiace per tua madre. = I’m sorry about your mother.
• Mi dispiace per quello che è successo. = I’m sorry about what happened.

This is a good pattern to memorize, because you can reuse it in many real conversations.
