Δεν είναι εύκολο να συνδυάζεις ταξίδια και ξεκούραση.

Να is a very common particle in Modern Greek. It often introduces a subordinate verb, especially where English might use an infinitive such as to combine.

So in:

Δεν είναι εύκολο να συνδυάζεις...

the part να συνδυάζεις corresponds roughly to to combine / combining.

Modern Greek does not have an infinitive like English does, so instead of saying a single verb form meaning to combine, Greek uses να + verb.

Συνδυάζεις is the 2nd person singular form of the verb συνδυάζω, meaning to combine.

It literally means you combine or you are combining.

In this sentence, though, it is not necessarily talking about you personally. Greek often uses the 2nd person singular in a general sense, a bit like English when you try to combine... or combining... in general.

So the sentence can feel like:

• It isn’t easy to combine travel and rest
• or more literally, It isn’t easy when you combine travel and rest

Because Modern Greek normally expresses this idea with να + a finite verb, not with an infinitive.

English:

• to combine travel and rest

Greek:

• να συνδυάζεις ταξίδια και ξεκούραση

So even though συνδυάζεις is grammatically a you form, the whole phrase functions where English would use an infinitive.

This is one of the most important differences between English and Greek grammar.

In Δεν είναι εύκολο να..., εύκολο is neuter singular because Greek often uses the neuter singular adjective in impersonal expressions.

So:

• είναι εύκολο = it is easy
• δεν είναι εύκολο = it is not easy

The it here is not a real noun. It is just an impersonal idea, so Greek uses the neuter singular form εύκολο.

Compare:

• Το μάθημα είναι εύκολο = The lesson is easy
  Here εύκολο agrees with το μάθημα, which is neuter.
• Η άσκηση είναι εύκολη = The exercise is easy
  Here the adjective changes to feminine: εύκολη.

But in your sentence, there is no specific noun like lesson or exercise, so the impersonal neuter εύκολο is used.

Δεν is the standard negation used with verbs in ordinary statements.

So:

• είναι εύκολο = it is easy
• δεν είναι εύκολο = it is not easy

Greek mainly uses:

• δεν with indicative-style statements
• μη(ν) in other contexts, such as prohibitions or after certain particles

Here we have a normal statement, so δεν is correct.

This is mainly about how the nouns are naturally used.

• ταξίδια = trips / travel experiences
• ξεκούραση = rest

In both Greek and English, some nouns are commonly used as countable plurals, while others are more naturally uncountable or abstract.

So Greek is treating:

• ταξίδια as multiple trips or travel activities
• ξεκούραση as the general idea of rest

That is why the combination sounds natural: ταξίδια και ξεκούραση = travel/trips and rest

You could imagine other contexts with different number choices, but this version is very natural.

Greek often leaves out the article when speaking about things in a general sense.

So:

• ταξίδια και ξεκούραση = travel/trips and rest in general

If you added articles, the meaning could become more specific or context-dependent:

• τα ταξίδια και η ξεκούραση

This might sound more like the trips and the rest, referring to something already known in context.

Without articles, the sentence sounds broad and general, which fits the meaning very well.

Not necessarily. Greek present forms often express:

• habitual action
• general truth
• ongoing/repeated activity

Here να συνδυάζεις does not mean only to be combining right now. It suggests the general act or ongoing challenge of combining travel and rest.

So the sentence is talking about a general reality: It’s not easy to combine travel and rest.

If you wanted to refer more to a single, complete act, Greek might use another form, such as να συνδυάσεις, depending on context.

This is a very useful question, because it involves aspect, which is central in Greek.

• να συνδυάζεις = imperfective aspect
• να συνδυάσεις = perfective aspect

Very roughly:

• να συνδυάζεις focuses on the process, repeated situation, or general activity
• να συνδυάσεις focuses more on a single completed event or achievement

So:

Δεν είναι εύκολο να συνδυάζεις ταξίδια και ξεκούραση.
means something like:
It’s not easy to be combining / to combine in general travel and rest.

While:

Δεν είναι εύκολο να συνδυάσεις ταξίδια και ξεκούραση.
could sound more like:
It’s not easy to manage to combine travel and rest in a particular case.

In many contexts, both may be possible, but they do not feel exactly the same.

Yes. Greek word order is more flexible than English word order, although not completely free.

The original: Δεν είναι εύκολο να συνδυάζεις ταξίδια και ξεκούραση.

is very natural and neutral.

You might also hear variations depending on emphasis, for example:

• Ταξίδια και ξεκούραση δεν είναι εύκολο να συνδυάζεις.

This gives more emphasis to travel and rest.

But for a learner, the original order is the best one to remember because it is straightforward and idiomatic.

Yes, συνδυάζω is a common and useful verb. It means to combine, to match, or to bring together.

Examples:

• συνδυάζω δουλειά και οικογένεια = I combine work and family
• συνδυάζει το κλασικό με το μοντέρνο = it combines the classic with the modern
• αυτό το χρώμα δεν συνδυάζεται εύκολα = this color is not easy to match

So in your sentence, it is used in a very natural everyday way.

A Greek speaker would hear it as a general observation or piece of advice about life. It sounds natural, neutral, and slightly thoughtful.

It does not sound like a very formal sentence, but it is also not slangy. It works well in normal conversation and writing.

The use of να συνδυάζεις helps give it that broad, general meaning: In life, combining travel and rest is not easy.

So the sentence feels less like it is about one specific event and more like a general truth or common difficulty.
