Tolgo il pane dal congelatore e lo lascio scongelare sul tavolo.

Because Italian often drops the subject pronoun when it is clear from the verb ending.

• tolgo = I remove / I take out
• The -o ending already tells you the subject is I

So Io tolgo il pane... is possible, but usually unnecessary unless you want emphasis, contrast, or clarity.

Tolgo is the 1st person singular present of togliere.

Here it means something like:

• I take out
• I remove

So Tolgo il pane dal congelatore literally means I remove the bread from the freezer.

A native English speaker may expect prendo (I take) or tiro fuori (I pull out / take out), and those can work in some contexts, but togliere is very natural when you mean removing something from somewhere.

Italian uses the definite article much more often than English.

So il pane can mean:

• the bread
• or, depending on context, the bread I’m dealing with / that specific bread

In English, we often omit the article in similar situations, but in Italian it is usually required.

Dal = da + il

It means from the.

So:

• da = from
• il congelatore = the freezer
• dal congelatore = from the freezer

Italian commonly combines prepositions with definite articles:

• da + il = dal
• su + il = sul
• a + il = al
• di + il = del

Yes. Il congelatore is the standard Italian word for freezer.

You may also hear freezer in everyday speech, especially in informal contexts, but congelatore is the normal Italian word.

Be careful not to confuse:

• frigorifero = fridge / refrigerator
• congelatore = freezer

Lo refers back to il pane.

It is a direct object pronoun meaning it.

Because pane is:

• masculine
• singular

the correct pronoun is lo.

So:

• il pane → lo
• Tolgo il pane... e lo lascio... = I take out the bread... and leave it...

In Italian, object pronouns like lo, la, li, le usually come before a conjugated verb.

So:

• lo lascio = I leave it

That is the normal pattern.

With a verb like lasciare followed by an infinitive, Italian sometimes also allows the pronoun attached to the infinitive:

• lo lascio scongelare
• lascio scongelarlo

Both are possible, but lo lascio scongelare is very natural and common.

Because the sentence means I leave it to thaw / I let it thaw, not I thaw it in an active, direct way.

Compare:

• Lo scongelo = I thaw it
• Lo lascio scongelare = I leave it to thaw / let it thaw

The second version suggests you are not doing the thawing yourself directly; you are simply putting it somewhere and allowing the process to happen.

That matches the rest of the sentence:

• sul tavolo = on the table

So the idea is: you take the bread out and let it thaw on the table.

Because after lasciare in this structure, Italian uses an infinitive.

This is similar to English patterns like:

• I let it thaw
• I make it thaw
• I watch it thaw

In Italian:

• lascio = I let / I leave
• scongelare = to thaw

So lo lascio scongelare literally works like I let it thaw.

Yes. In many contexts, scongelare can be translated as either:

• to thaw
• to defrost

The best English choice depends on context.

In this sentence, since the bread is left on the table, thaw sounds especially natural in English.

Sul = su + il

It means on the.

So:

• su = on
• il tavolo = the table
• sul tavolo = on the table

This is another example of an Italian preposition + article contraction.

Yes, often you can.

• sul tavolo = on the table
• sopra il tavolo = on top of / above the table

In many everyday situations, both can work. But there is a slight difference:

• sul tavolo usually emphasizes location on the surface
• sopra il tavolo can emphasize being on top of it, and sometimes even just above it depending on context

Here, sul tavolo is the most natural choice.

It can be either, depending on context.

Tolgo il pane dal congelatore e lo lascio scongelare sul tavolo could mean:

• I’m taking the bread out of the freezer and leaving it to thaw on the table
  or
• I take the bread out of the freezer and leave it to thaw on the table as a regular routine

Italian present tense, like English present in some contexts, can describe:

• a current action
• a habitual action
• a step in a process or instruction

Yes. A few natural alternatives are:

• Tiro fuori il pane dal congelatore e lo lascio scongelare sul tavolo.
  Slightly more like I take/pull the bread out of the freezer

• Tolgo il pane dal freezer e lo lascio scongelare sul tavolo.
  Same meaning, with freezer instead of congelatore

• Tolgo il pane dal congelatore e lo faccio scongelare sul tavolo.
  Possible, but faccio scongelare can sound a bit more causative; lascio scongelare is more natural here

The original sentence is completely natural and idiomatic.
