Η ευκολία δεν σημαίνει πάντα καλό αποτέλεσμα.

Greek very often uses the definite article where English might not.

• η = the for feminine singular nouns
• ευκολία = ease, easiness, convenience

So Η ευκολία literally looks like the ease, but in Greek this can still express a general idea, like ease in general.

This is very common in Greek:

• Η αγάπη είναι σημαντική. = Love is important.
• Η υπομονή βοηθά. = Patience helps.

So here, Η ευκολία means the concept of ease, not one specific ease.

ευκολία is a noun. It means ease, easiness, or sometimes convenience.

It is related to the adjective:

• εύκολος = easy (masculine)
• εύκολη = easy (feminine)
• εύκολο = easy (neuter)

So the relationship is similar to:

• easy → ease
• simple → simplicity

Examples:

• Είναι εύκολο. = It is easy.
• Η ευκολία δεν αρκεί. = Ease is not enough.

δεν is the basic Greek word for not before verbs in the present tense and many other non-subjunctive forms.

So:

• σημαίνει = means
• δεν σημαίνει = does not mean

Greek does not use a separate word like English do/does for this kind of negation. It simply puts δεν before the verb.

Compare:

• Σημαίνει κάτι. = It means something.
• Δεν σημαίνει κάτι κακό. = It does not mean something bad.

σημαίνει comes from σημαίνω, which commonly means:

• to mean
• to signify
• to indicate

In this sentence, σημαίνει is best understood as means.

So the structure is:

• Η ευκολία = ease
• δεν σημαίνει = does not mean
• πάντα = always
• καλό αποτέλεσμα = a good result

Greek uses σημαίνω in many contexts:

• Τι σημαίνει αυτή η λέξη; = What does this word mean?
• Αυτό σημαίνει πολλά. = That means a lot.

πάντα means always, and adverbs in Greek are fairly flexible in position.

Here:

• Η ευκολία δεν σημαίνει πάντα καλό αποτέλεσμα.

This placement is very natural and means:

• Ease does not always mean a good result.

The adverb πάντα is placed near the verb phrase to modify the whole idea of does not mean.

If you moved it, the sentence might still be understandable, but this version sounds natural and standard.

Because αποτέλεσμα is a neuter noun.

In Greek, adjectives must agree with the noun they describe in:

• gender
• number
• case

Since αποτέλεσμα is:

• neuter
• singular

the adjective must also be:

• neuter singular → καλό

So:

• καλός = masculine
• καλή = feminine
• καλό = neuter

That is why Greek says:

• καλό αποτέλεσμα = good result

It is in the accusative case, because it is the direct object of the verb σημαίνει.

The verb answers the question:

• Ease does not always mean what?
• καλό αποτέλεσμα

So καλό αποτέλεσμα is the object.

A useful detail: for many neuter singular nouns, the nominative and accusative forms look the same. So even though it is accusative here, it looks identical to the dictionary form.

Because Greek is expressing a good result in a general sense, not the good result.

So:

• καλό αποτέλεσμα = a good result
• το καλό αποτέλεσμα = the good result

In a general statement like this, leaving out the article is very natural.

The sentence is making a broad point:

• Ease does not always lead to a good result

not:

• Ease does not always mean the specific good result

It depends on context.

ευκολία can mean:

• ease
• easiness
• convenience

In this sentence, ease is usually the best choice, because the idea is that something being easy does not automatically produce a good result.

So the nuance is closer to:

• The fact that something is easy than
• practical convenience

Yes, Greek word order is more flexible than English word order, but not all versions sound equally natural.

The original:

• Η ευκολία δεν σημαίνει πάντα καλό αποτέλεσμα.

is clear and natural.

You could move things around for emphasis, but the tone may change. For example:

• Η ευκολία πάντα δεν σημαίνει καλό αποτέλεσμα sounds awkward in standard usage.
• Καλό αποτέλεσμα δεν σημαίνει πάντα η ευκολία is understandable but marked and much less neutral.

So for learners, the original order is the safest and most natural.

Because its subject is Η ευκολία, which is singular.

Greek verbs agree with their subject in person and number.

Here:

• Η ευκολία = singular
• so the verb is σημαίνει = it means

If the subject were plural, the verb would also be plural:

• Οι ευκολίες δεν σημαίνουν πάντα καλό αποτέλεσμα.
• Easy solutions / conveniences do not always mean a good result.

Yes, it expresses a general truth or general principle.

Greek, like English, often uses the present tense for this:

• Η ευκολία δεν σημαίνει πάντα καλό αποτέλεσμα.
• Ease does not always mean a good result.

This is the normal tense for statements that are generally true, habitual, or timeless.

A simple pronunciation guide is:

i ef-ko-LEE-a then SEE-me-nee PAN-da ka-LO a-po-TE-les-ma

A few notes:

• η sounds like ee
• ευ here sounds like ef because of the following consonant
• δεν is pronounced roughly then with a soft Greek th/dh sound, not a hard English d
• the stress falls on:
  • ευκολία
  • σημαίνει
  • πάντα
  • καλό
  • αποτέλεσμα
