Se non avessi il raffreddore, verrei con te dal panettiere e poi dal barista.

Because this sentence expresses an unreal or hypothetical situation in the present: the speaker actually does have a cold, so they are imagining the opposite.

Italian commonly uses this pattern for present unreal conditions:

• se + imperfect subjunctive
• conditional present in the main clause

So:

• Se non avessi il raffreddore, verrei...
• If I didn’t have a cold, I would come...

Here:

• avessi = imperfect subjunctive of avere
• verrei = present conditional of venire

This is a very standard structure in Italian.

Avessi is the imperfetto del congiuntivo of avere.

The imperfect subjunctive forms of avere are:

• io avessi
• tu avessi
• lui/lei avesse
• noi avessimo
• voi aveste
• loro avessero

In this sentence, io avessi is understood because Italian often drops subject pronouns.

So se non avessi il raffreddore literally means if I were not having the cold, but in natural English: if I didn’t have a cold.

Verrei is the present conditional of venire.

It means I would come.

The sentence follows the classic hypothetical pattern:

• Se non avessi... = if I didn’t have...
• verrei... = I would come...

So the two parts match grammatically:

• imperfect subjunctive in the if-clause
• present conditional in the result clause

Because Italian often uses venire where English uses come, especially when the movement is understood relative to the person being addressed.

• verrei con te = I’d come with you
• andrei con te = I’d go with you

Both can be possible in some contexts, but verrei con te is very natural when speaking directly to someone and joining them.

So if I say to you:

• Verrei con te
  I’m framing it as coming along with you

That matches English I’d come with you very well.

That is just a normal Italian pattern.

With many illnesses or physical conditions, Italian uses the definite article:

• ho il raffreddore = I have a cold
• ho la febbre = I have a fever
• ho il mal di testa = I have a headache

So il raffreddore is exactly what Italian normally says here.

Even though English does not usually use the, Italian does.

No. It is just a normal negation inside the if-clause.

• se = if
• non = not
• avessi = I had

So:

• se non avessi il raffreddore = if I didn’t have a cold

There is only one negative element here: non.

Because Italian usually omits subject pronouns when the verb ending already makes the subject clear.

• avessi already tells you it is I
• verrei also already tells you it is I

So io is not necessary.

You could say:

• Se io non avessi il raffreddore, verrei...

But that sounds more emphatic. The version without io is more neutral and natural.

It can mean either, depending on context, and that is very common in Italian.

da + article + person/profession often means:

• to that person
• or to that person’s place/business

So:

• dal panettiere can mean to the baker or, more naturally in many contexts, to the bakery / baker’s shop

This is a very common Italian structure:

• dal medico = to the doctor / doctor’s office
• dal dentista = to the dentist / dentist’s office
• dal parrucchiere = to the hairdresser / hair salon

So dal panettiere is perfectly normal.

A learner may notice that al bar is often more common when talking about going to a café/bar as a place.

However, dal barista is still understandable and can mean:

• to the barista
• to the barista’s place/counter
• to the café run by or associated with the barista

So grammatically it works the same way as dal panettiere: da + person/profession.

That said, in everyday speech, many Italians would very often say:

• al bar

if the focus is the place rather than the person.

Because each noun has its own prepositional phrase:

• dal panettiere
• dal barista

Italian often repeats the preposition/article combination in coordinated phrases, especially when it sounds clearer or more natural.

So:

• dal panettiere e poi dal barista

is clearer and more idiomatic than trying to make one dal cover both.

Poi means then or afterwards.

So:

• dal panettiere e poi dal barista means
• to the baker’s and then to the barista / bar

It simply shows the order of actions.

Not in this form. This sentence is about a present hypothetical situation.

• Se non avessi il raffreddore, verrei... = If I didn’t have a cold, I would come...

If you wanted a past hypothetical, Italian would normally use:

• Se non avessi avuto il raffreddore, sarei venuto con te... = If I hadn’t had a cold, I would have come with you...

So the original sentence is specifically about now, not about a past missed action.

Yes. Verrei con te is completely natural.

Italian word order is often flexible, but this is a very standard arrangement:

• verrei con te dal panettiere
• I’d come with you to the baker’s

You might sometimes see other orders for emphasis, but nothing is unusual here.
