Το δυνατό σημείο είναι η κατανόηση κειμένου.

Because it agrees with σημείο, and σημείο is a neuter singular noun.

• δυνατός = masculine
• δυνατή = feminine
• δυνατό = neuter

So:

• το δυνατό σημείο = the strong point

In Greek, adjectives must match the noun they describe in gender, number, and case.

It is the subject of the sentence:

• Το δυνατό σημείο = the strong point
• είναι = is
• η κατανόηση κειμένου = reading/text comprehension

So the structure is:

[subject] + [is] + [complement]

Greek often works much like English with sentences using είμαι.

Greek uses the definite article much more often than English.

Here, both noun phrases are definite expressions:

• το δυνατό σημείο = the strong point
• η κατανόηση κειμένου = the comprehension of text / reading comprehension

With the verb είναι, it is very common for both sides of the sentence to have articles, especially when both are treated as complete noun phrases.

So even if English might sometimes sound more natural with fewer articles, Greek often keeps them.

Because grammatical gender in Greek is a property of the noun itself. The noun κατανόηση is simply a feminine noun, so it takes the feminine article η.

This does not mean the idea itself is feminine in any real-world sense. It is just part of Greek grammar.

κειμένου is in the genitive singular.

It comes from the noun:

• το κείμενο = the text

Its genitive singular is:

• του κειμένου = of the text

In the sentence, the article is omitted, so we get:

• κατανόηση κειμένου = comprehension of text / text comprehension

Greek very often uses the genitive after nouns to express something like English of:

• η κατανόηση κειμένου = the comprehension of text
• η γνώση ελληνικών = the knowledge of Greek
• η ανάγνωση βιβλίου = the reading of a book

Because after κατανόηση, Greek uses a genitive complement.

Compare:

• το κείμενο = the text
• του κειμένου = of the text

After a noun like κατανόηση (understanding/comprehension), Greek does not normally use the plain nominative/accusative form κείμενο here. It uses the genitive idea:

• κατανόηση κειμένου = comprehension of text

So κείμενο would be the wrong form in this structure.

Because Greek often leaves out the article when the meaning is general rather than specific.

So:

• κατανόηση κειμένου = text comprehension / comprehension of text in general
• κατανόηση του κειμένου = comprehension of the text, meaning a specific text

This is an important difference.

In your sentence, the meaning is probably broad, like a skill area or school subject, so κειμένου without the article is natural.

Yes, usually.

• η κατανόηση κειμένου = text comprehension in general
• η κατανόηση του κειμένου = comprehension of the specific text

So if you are talking about a general strength, such as a student's skill, κατανόηση κειμένου is the better choice.

If you are talking about understanding one particular passage or document, then του κειμένου would make more sense.

Yes, it is a very common educational expression.

It is often used for:

• reading comprehension
• text comprehension
• understanding written material

So although it is grammatically transparent, it also functions like a standard phrase, especially in school and exam contexts.

Yes. Greek word order is more flexible than English.

For example, you could also say:

• Η κατανόηση κειμένου είναι το δυνατό σημείο.

This has the same basic meaning, but the focus may shift slightly depending on context.

Greek uses word order for emphasis more freely than English does. Still, your original sentence is perfectly natural.

Good question. With είναι, both parts can look similar, so you often depend on:

• context
• meaning
• emphasis

In this sentence, το δυνατό σημείο is understood as the subject because the sentence is presenting what the strong point is.

So the logic is:

• The strong point is ... not
• The reading comprehension is the strong point

Even though Greek grammar allows flexibility, context usually makes the intended subject clear.

In a normal complete sentence like this, είναι is usually included.

• Το δυνατό σημείο είναι η κατανόηση κειμένου.

Greek can omit forms of to be in some very informal contexts, headings, notes, or labels, but in standard full sentences you normally keep είναι.

So here it is the expected form.

The dictionary form is usually the masculine singular:

• δυνατός, δυνατή, δυνατό

That is how Greek adjectives are commonly listed.

So if you want to look it up, search for δυνατός.

Yes. Literally:

• δυνατό = strong
• σημείο = point

Together, δυνατό σημείο is the normal Greek equivalent of strong point, meaning someone's strength or best area.

So this is both literal and idiomatic.

Sometimes, but δυνατό σημείο is the standard idiomatic phrase.

For example, a learner might wonder about ισχυρό, since it can also mean strong. But ισχυρό σημείο is not the usual expression for strong point in this sense.

So if you mean someone's strength, δυνατό σημείο is the natural phrase to learn.

σημείο is pronounced roughly see-MEE-o.

A few useful points:

• σ = s
• η sounds like ee
• ει also sounds like ee in Modern Greek

So although σημείο has several vowels, the stress falls on -εί-.

It may look complicated at first, but this spelling is completely normal in Greek.

A rough pronunciation guide is:

to thi-na-TO see-MEE-o EE-ne ee ka-ta-NO-ee-see kee-ME-nou

More carefully:

• Το δυνατό σημείο
• είναι
• η κατανόηση κειμένου

A few notes:

• δ in Modern Greek sounds like the th in this
• η, ι, ει, οι, υ often sound like ee
• αι usually sounds like e
• stress matters, so pay attention to the accent marks

Because κατανόηση focuses on understanding, not just the act of reading.

Compare:

• διάβασμα = reading/studying
• κατανόηση κειμένου = comprehension of a text

So this phrase is specifically about the skill of understanding what you read, not merely reading words aloud or studying in general.

It sounds neutral to fairly formal, and very natural in educational or evaluative contexts.

For example, it would fit well in:

• school reports
• exam feedback
• skill assessments
• language-learning contexts

It is not overly stiff, but it is more polished than casual everyday chat.

Yes, probably.

Your sentence says:

• Το δυνατό σημείο = the strong point

If you want one strong point or a strong point, Greek would likely use a different structure, such as:

• Ένα δυνατό σημείο είναι η κατανόηση κειμένου.

So the article matters:

• το = the
• ένα = a / one

The most useful grammar points are probably these:

1. Adjective agreement

   • δυνατό matches σημείο

2. Greek article usage

   • Greek uses articles very often

3. Genitive after a noun

   • κατανόηση κειμένου = comprehension of text

4. General vs specific meaning

   • κειμένου = text in general
   • του κειμένου = a specific text

This sentence is short, but it shows several very common Greek patterns.
