Si entens aquest exemple, podràs fer un resum millor demà.

Si means if. It introduces a condition:

• Si entens aquest exemple = If you understand this example

This is a very common pattern in Catalan:

• Si estudies, aprovaràs. = If you study, you will pass.
• Si plou, no sortirem. = If it rains, we won’t go out.

Entens is the 2nd person singular present tense form of entendre (to understand).

The subject is an implied you:

• (tu) entens = you understand

Catalan often drops subject pronouns when the verb already makes the subject clear. So:

• Si entens aquest exemple...
  literally means
• If (you) understand this example...

The infinitive entendre would mean to understand, not you understand.

Catalan usually leaves out subject pronouns unless they are needed for emphasis or clarity.

So instead of saying:

• Si tu entens aquest exemple...

it is more natural to say:

• Si entens aquest exemple...

The verb ending -ens already tells you it means you (tu).

The same happens later with podràs:

• podràs = you will be able to

So the sentence has two implied you subjects.

Aquest means this and is a demonstrative adjective placed before a masculine singular noun.

Here it modifies exemple, which is masculine singular:

• aquest exemple = this example

Why not the others?

• aquesta is feminine singular:
  
  • aquesta idea = this idea
• això means this / this thing, but it stands alone as a pronoun, not before a noun:
  • Això és difícil. = This is difficult.

So:

• aquest exemple = correct
• això exemple = incorrect

Podràs fer literally means you will be able to do / make.

It uses the common structure:

• poder + infinitive

So:

• podràs = you will be able to
• fer = do / make

Together:

• podràs fer = you will be able to make/do

Catalan often uses poder the same way English uses can / be able to:

• Pots venir. = You can come.
• Podràs sortir demà. = You will be able to go out tomorrow.

In this sentence, it suggests ability resulting from understanding the example.

Podràs is the future tense of poder (to be able to / can), in the tu form.

So:

• jo podré = I will be able to
• tu podràs = you will be able to
• ell/ella podrà = he/she will be able to

The accent in podràs is important. It shows stress and distinguishes the correct form.

In this sentence, the structure is:

• Si + present, future

That is very normal in Catalan:

• Si véns, t’ajudaré. = If you come, I’ll help you.
• Si estudies, aprovaràs. = If you study, you’ll pass.

So Catalan works like English here:

• condition clause: present
• result clause: future

You generally do not use future after si in this type of sentence.

Fer un resum means to make / do a summary, or more naturally in English, to write a summary or to produce a summary.

• fer = do / make
• un resum = a summary

Catalan uses fer in many places where English may choose a more specific verb.

Examples:

• fer una pregunta = ask a question
• fer un error = make an error
• fer un resum = make / write a summary

So even if fer literally means do/make, the full phrase should be understood naturally.

In Catalan, many adjectives usually come after the noun.

So:

• un resum millor = a better summary

Here:

• resum = summary
• millor = better

This post-noun position is normal. Compare:

• un llibre interessant = an interesting book
• una idea bona = a good idea

That said, adjective position in Catalan can sometimes vary for stylistic or meaning reasons, but in this sentence un resum millor is the straightforward, natural order.

Here millor is an adjective, meaning better, because it describes resum.

• un resum millor = a better summary

Catalan millor can also be used in other ways:

• as an adverb: Ho fa millor. = He/She does it better.
• in expressions: millor que = better than

In this sentence, though, it is modifying the noun resum.

Demà means tomorrow. Putting it at the end is very natural in Catalan.

So:

• podràs fer un resum millor demà = you’ll be able to make a better summary tomorrow

Time expressions are often flexible in Catalan, but the end position is common and natural. You could move it for emphasis, but the given order is neutral.

In the most natural reading, demà goes with the second part:

• podràs fer un resum millor demà
  = you will be able to make a better summary tomorrow

So the idea is:

• if you understand this example now,
• tomorrow you’ll be able to write a better summary.

That is the most likely interpretation.

With subject pronouns added, it would be:

• Si tu entens aquest exemple, tu podràs fer un resum millor demà.

This is grammatically possible, but usually less natural unless you want emphasis, contrast, or clarity.

For example, you might say tu to contrast with someone else:

• Si tu entens aquest exemple, tu podràs fer un resum millor demà, però ell no.

Normally, the version without pronouns is preferred.

Yes. The accents are part of the correct spelling and pronunciation.

• podràs
• demà

In Catalan, written accents show which syllable is stressed and sometimes distinguish words. If you leave them out, the word may be misspelled or harder to interpret correctly.

So it is important to learn them as part of the word, not as optional marks.
