Προτιμώ να αγοράσω λίγα αλλά καλά ρούχα παρά να ξοδεύω χρήματα σε πράγματα χωρίς στυλ.

In Modern Greek, verbs like προτιμώ are usually followed by a να-clause instead of an infinitive.

English says:

• I prefer to buy...
• I prefer spending...

Greek normally says:

• Προτιμώ να αγοράσω...
• Προτιμώ να ξοδεύω...

So να introduces the next verb phrase. Greek does not use the old infinitive the way English uses to buy, to spend, etc.

This is a very important Greek point: the two forms show different aspect.

• να αγοράσω = aorist/perfective aspect
  It presents the action as a single whole or completed event: to buy.
• να ξοδεύω = imperfective aspect
  It presents the action as ongoing, repeated, habitual, or general: to be spending / to spend regularly.

So the sentence suggests:

• buying a few good clothes = a more bounded, one-time kind of action
• spending money on things without style = a repeated or general habit

That is why the speaker chooses:

• αγοράσω for the first action
• ξοδεύω for the second

Greek often makes this aspect choice where English does not clearly show it.

Yes, it could, but the meaning would shift slightly.

• να ξοδεύω χρήματα suggests spending money in general / as a habit
• να ξοδέψω χρήματα would suggest to spend money once / in a specific case

So:

• Προτιμώ ... παρά να ξοδεύω χρήματα...
  = I prefer ... rather than spending money on such things in general

• Προτιμώ ... παρά να ξοδέψω χρήματα...
  = I prefer ... rather than spend money on such things (in a more single-event sense)

Both are grammatical, but the original sentence sounds natural because it contrasts a targeted purchase with wasteful spending as a general behavior.

Because ρούχα is neuter plural.

Greek adjectives and words like λίγος must agree with the noun in gender, number, and case.

The forms are:

• λίγος = masculine singular
• λίγη = feminine singular
• λίγο = neuter singular
• λίγοι = masculine plural
• λίγες = feminine plural
• λίγα = neuter plural

Since ρούχα is neuter plural, the correct form is:

• λίγα ρούχα = few clothes

Here καλά is an adjective, not an adverb.

It agrees with ρούχα, which is neuter plural:

• καλός = masculine singular
• καλή = feminine singular
• καλό = neuter singular
• καλοί / καλές / καλά = plural forms

So:

• καλά ρούχα = good clothes

This can confuse learners because καλά is also the form of the adverb well. But in this sentence it is clearly an adjective describing the noun ρούχα.

Greek often leaves out the article when speaking in a general or indefinite way.

Here the speaker is not talking about:

• specific clothes
• specific money
• specific things already known to both speakers

Instead, the meaning is general:

• a few good clothes
• money
• things without style

So no article is needed.

If you added articles, the meaning could become more specific depending on context.

Here παρά means rather than.

It links two alternatives after a comparison of preference:

• Προτιμώ ... παρά ...
• I prefer ... rather than ...

In this sentence:

• Προτιμώ να αγοράσω ... παρά να ξοδεύω ...
• I prefer to buy ... rather than spend ...

So παρά introduces the thing the speaker rejects in comparison with what they prefer.

Because παρά is connecting two verb phrases, and each verb phrase needs its own να in Greek.

So you get:

• να αγοράσω
• παρά να ξοδεύω

You cannot usually just say:

• Προτιμώ να αγοράσω ... παρά ξοδεύω ...

The second verb also needs the να-clause structure.

Yes. English money is grammatically singular/uncountable, but Greek χρήματα is a plural form.

So Greek says:

• χρήματα = money

Even though it is plural in form, you usually translate it simply as money, not monies.

This is very common and natural in Greek:

• Δεν έχω χρήματα. = I don’t have money.
• Ξοδεύει πολλά χρήματα. = He/She spends a lot of money.

The preposition σε usually means in, on, at, to depending on context. Here it means on, as in:

• spend money on something
• ξοδεύω χρήματα σε κάτι

So:

• σε πράγματα = on things

After σε, the noun appears in the form used for the modern accusative construction:

• σε πράγματα

This is the normal way Greek expresses the object of spending in this context.

Χωρίς means without.

So:

• πράγματα χωρίς στυλ = things without style

There is no article because the phrase is describing the things in a general way. It is not:

• without the style
  but simply
• without style

Also, στυλ is commonly used in Greek as an indeclinable loanword, so it stays the same form here.

Αγοράσω is the 1st person singular aorist subjunctive form used after να.

You can think of it as coming from the verb αγοράζω = I buy.

Compare:

• αγοράζω = I buy / I am buying
• να αγοράζω = to be buying / to buy habitually
• να αγοράσω = to buy (as a complete act)

Because it follows να, you do not translate it as a plain present or past tense. Its function depends on the whole structure:

• Προτιμώ να αγοράσω = I prefer to buy

Not completely, but this order is very natural.

• λίγα = few
• αλλά = but
• καλά = good
• ρούχα = clothes

So the phrase emphasizes:

• not many clothes,
• but good ones.

The structure λίγα αλλά καλά ρούχα sounds smooth and idiomatic because it sets up a contrast:

• few, but good, clothes

Greek word order is flexible, but this version is probably the most natural one here.

Because it directly contrasts two qualities of the same noun:

• λίγα = few
• καλά = good

So:

• λίγα αλλά καλά ρούχα = few but good clothes

This is just like English:

• a small but good selection
• few but quality items

The speaker is saying that quantity matters less than quality.

Στυλ is a very common word in Modern Greek, borrowed from French/English-type sources, and it usually behaves as an indeclinable noun in everyday use.

That means its form often stays the same:

• στυλ
• χωρίς στυλ
• με στυλ

So learners should not expect a full set of changing endings the way many native Greek nouns have.

Because after προτιμώ, Greek normally needs a full verb construction with να if another finite verb follows.

So:

• Προτιμώ να αγοράσω... is correct
• Προτιμώ αγοράσω... is not standard Greek

This is one of the big differences from English. English uses to buy, but Greek uses να + verb.

The sentence has this pattern:

• Προτιμώ
  = I prefer
• να αγοράσω λίγα αλλά καλά ρούχα
  = to buy a few but good clothes
• παρά να ξοδεύω χρήματα σε πράγματα χωρίς στυλ
  = rather than spend money on things without style

So the overall structure is:

I prefer + να-clause + παρά + να-clause

That is a very useful pattern to remember for expressing preference in Greek.
