Τώρα σε καταλαβαίνω περισσότερο.

σε is the weak form of the direct object pronoun meaning you (singular).

So in σε καταλαβαίνω, the structure is literally:

• σε = you
• καταλαβαίνω = I understand

Greek normally uses this short object pronoun before the verb, so σε καταλαβαίνω is the natural way to say I understand you.

If you were speaking to more than one person, you would use σας instead:

• Τώρα σας καταλαβαίνω περισσότερο. = Now I understand you more / better.

In standard modern Greek, these short object pronouns usually go before a finite verb:

• σε καταλαβαίνω
• τον βλέπω
• μας ακούνε

So καταλαβαίνω σε is not the normal standard order here.

A very important rule for learners is:

• short object pronouns like με, σε, τον, τη, το, μας, σας, τους usually come before the conjugated verb

Example:

• Σε ξέρω. = I know you.
• Δεν σε ξέρω. = I don’t know you.

καταλαβαίνω is the 1st person singular present tense of καταλαβαίνω:

• I understand

The ending -ω here shows I.

A few present-tense forms:

• (εγώ) καταλαβαίνω = I understand
• (εσύ) καταλαβαίνεις = you understand
• (αυτός/αυτή/αυτό) καταλαβαίνει = he/she/it understands
• (εμείς) καταλαβαίνουμε = we understand
• (εσείς) καταλαβαίνετε = you understand
• (αυτοί) καταλαβαίνουν = they understand

Greek often drops the subject pronoun, so you usually just say καταλαβαίνω, not εγώ καταλαβαίνω, unless you want emphasis.

Greek usually does not need the subject pronoun, because the verb ending already tells you who the subject is.

So:

• καταλαβαίνω already means I understand
• καταλαβαίνεις already means you understand

You can add εγώ if you want contrast or emphasis:

• Εγώ τώρα σε καταλαβαίνω περισσότερο. = I understand you better now / As for me, I understand you better now

So leaving out εγώ is completely normal.

Here περισσότερο means more, and in natural English the whole sentence is often translated as Now I understand you better.

Grammatically, περισσότερο is functioning as an adverb, modifying the verb καταλαβαίνω. It tells us the degree of understanding.

So the idea is:

• I understand you more than before
• in smoother English: I understand you better now

Greek often uses περισσότερο where English might prefer better.

Good question. Both can make sense, but they are not exactly identical in feel.

• περισσότερο = more
• καλύτερα = better

So:

• Τώρα σε καταλαβαίνω περισσότερο. = Now I understand you more / better
• Τώρα σε καταλαβαίνω καλύτερα. = Now I understand you better

In real usage, καλύτερα may sound a bit more natural to an English speaker because English says understand better. But Greek can absolutely use περισσότερο to express greater degree.

You may also hear:

• Τώρα σε καταλαβαίνω πιο πολύ.

That is more conversational and also means Now I understand you more / better.

Here it is an adverb.

Why? Because it modifies the verb καταλαβαίνω (I understand), not a noun.

Compare:

• καταλαβαίνω περισσότερο = I understand more → adverb
• περισσότερα βιβλία = more books → adjective/determiner-like use with a noun

So in this sentence, περισσότερο is telling us how much or to what degree the understanding happens.

Τώρα literally means now, but in context it can do more than simply refer to time.

In this sentence it often suggests a contrast with the past:

• before, I didn’t understand you so well
• now, I do

So τώρα can carry the sense of:

• now
• at this point
• by now

It often introduces a change in state or attitude.

Yes. Greek word order is more flexible than English, though not completely free. The sentence can be rearranged for emphasis.

Standard neutral order:

• Τώρα σε καταλαβαίνω περισσότερο.

Other possible orders:

• Σε καταλαβαίνω περισσότερο τώρα.
• Τώρα καταλαβαίνω περισσότερο.
  (This only works if you is understood from context.)
• Περισσότερο σε καταλαβαίνω τώρα.
  (possible, but marked; gives emphasis)

The most neutral and natural version is the original:

• Τώρα σε καταλαβαίνω περισσότερο.

Changing word order usually changes focus or emphasis, not the basic meaning.

Usually, no. By default, it means:

• I understand you more than before
• or I understand you better now

If you wanted to say I understand you more than I understand someone else, Greek would usually make that comparison clearer, for example:

• Σε καταλαβαίνω περισσότερο από αυτόν. = I understand you more than him

Without an explicit comparison, listeners will normally understand περισσότερο as a comparison with an earlier situation.

It can be used very broadly, much like English understand.

It can mean:

• understanding what someone says
• understanding someone’s feelings
• understanding a situation or point of view

So Τώρα σε καταλαβαίνω περισσότερο could mean:

• I understand what you mean better now
• I understand your situation better now
• I understand you as a person better now

The exact nuance depends on context.

A simple learner-friendly pronunciation guide:

• Τώρα ≈ TO-ra
• σε ≈ se
• καταλαβαίνω ≈ ka-ta-la-VE-no
• περισσότερο ≈ pe-ri-SO-te-ro

Putting it together:

• TO-ra se ka-ta-la-VE-no pe-ri-SO-te-ro

A few stress points to notice:

• ΤΩρα
• καταλαΒΑΙνω
• περισΣΟτερο

Greek stress is very important, so try to keep the stressed syllables clear.

Yes, absolutely. It sounds natural.

Depending on style and situation, a speaker might also say:

• Τώρα σε καταλαβαίνω καλύτερα.
• Τώρα σε καταλαβαίνω πιο πολύ.

All of these are normal, with slightly different shades of style:

• περισσότερο = a bit more neutral/formal
• καλύτερα = very natural, often matching English better
• πιο πολύ = common and conversational

So the given sentence is correct and natural, but it is not the only way to express the idea.
