L’uomo lavora molto a marzo, ma la sera legge con calma.

Because uomo starts with a vowel sound. In Italian, il becomes l’ before most singular nouns beginning with a vowel:

• il libro → the book
• l’uomo → the man

The apostrophe shows that the vowel in il has been dropped.

Italian often leaves out subject pronouns when they are already clear from the verb form. This is very common.

Here, both verbs are third-person singular:

• lavora = (he/she) works
• legge = (he/she) reads

Since the sentence already starts with L’uomo, there is no need to add lui.

They match the subject L’uomo, which is third-person singular.

• lavorare → lavora = he works
• leggere → legge = he reads

So the pattern is:

• singular subject → singular verb form

This is just normal present-tense conjugation.

Here molto means a lot or very much, and it is being used as an adverb, not an adjective.

So:

• lavora molto = he works a lot

As an adverb, molto does not change for gender or number.

Compare:

• molti libri = many books → adjective/quantifier, so it changes
• lavora molto = works a lot → adverb, so it stays molto

In Italian, time expressions do not always use the same preposition that English uses. Here, a marzo is a normal way to say in March.

So:

• a marzo = in March

This is an idiomatic time expression. Even though English uses in, Italian often uses a in this kind of case.

With parts of the day, Italian often uses the definite article:

• la mattina
• il pomeriggio
• la sera

So la sera means in the evening or, in a habitual sentence like this, often in the evenings / every evening.

The article is a normal part of the expression.

In this sentence, it sounds habitual.

Because the verbs are in the present tense and the whole sentence describes a general pattern, la sera is understood as something like:

• in the evening
• in the evenings
• every evening

So the idea is not one single evening, but his usual routine.

Italian word order is flexible, especially with time expressions. Putting la sera before the verb highlights when he reads.

• La sera legge con calma = natural
• Legge con calma la sera = also possible

Both are understandable, but the original version gives a little more prominence to the time expression.

Literally, con calma means with calm. In natural English, that usually becomes:

• calmly
• in a relaxed way
• without rushing

Italian very often uses con + noun where English might prefer an adverb.

So:

• legge con calma = he reads calmly / at a relaxed pace

You could also say calmamente, but con calma is extremely common and sounds very natural.

Not necessarily. In Italian, the present tense can describe:

• what is happening now
• habits
• repeated actions
• general facts

In this sentence, it clearly describes a habit or regular pattern:

• he works a lot in March
• but in the evening he reads calmly

So this is best understood as a general routine, not a play-by-play description of the current moment.

Because ma means but, and it connects two contrasting ideas:

• L’uomo lavora molto a marzo
• ma la sera legge con calma

The comma helps show the pause and the contrast, just like in English. It is very natural punctuation here.
