Ο ύποπτος περιμένει.

Ο is the masculine singular definite article in the nominative case. In English, it usually corresponds to the.

So:

• Ο ύποπτος = the suspect

Here it marks ύποπτος as the subject of the sentence.

Yes. ύποπτος can be:

• an adjective meaning suspicious
• or an adjective used like a noun, meaning suspect

In this sentence, because it has the article Ο, it is being used as a noun:

• Ο ύποπτος = the suspect

This is very common in Greek: an adjective can become a noun when the context makes it clear.

No. Ο here is not the pronoun he. It is the article the.

So:

• Ο ύποπτος = the suspect
• he in Greek would be αυτός

Greek articles can look a little more noticeable than English the, so it is easy for learners to wonder if they are pronouns.

ύποπτος is:

• masculine
• singular
• nominative

That matches Ο, which is also masculine singular nominative.

This combination shows that the suspect is the subject of the sentence.

The adjective changes by gender:

• ο ύποπτος = the male suspect / the suspicious man
• η ύποπτη = the female suspect / the suspicious woman
• το ύποπτο = the suspicious thing

So Greek adjectives and articles must agree in gender, number, and case.

περιμένει is the verb, and it is:

• present tense
• active voice
• indicative mood
• 3rd person singular

It comes from the dictionary form περιμένω = to wait

So περιμένει means:

• he/she/it waits
• he/she/it is waiting

Which exact English translation fits best depends on context.

It can mean either one.

The Greek present tense often covers both:

• a general present: waits
• an ongoing action: is waiting

So Ο ύποπτος περιμένει could be understood as:

• The suspect waits
• The suspect is waiting

Context tells you which English version sounds more natural.

Because Greek usually does not need subject pronouns when the verb ending already shows the person and number.

περιμένει already tells you the subject is 3rd person singular:

• he waits
• she waits
• it waits

So Greek often leaves pronouns out unless they are needed for emphasis or contrast.

Yes, Greek could absolutely say Περιμένει if the context already made the subject clear.

But Ο ύποπτος περιμένει includes the subject in order to:

• identify who is waiting
• make the sentence clearer
• possibly add emphasis

So:

• Περιμένει. = He/She is waiting.
• Ο ύποπτος περιμένει. = The suspect is waiting.

A simple pronunciation guide is:

• Ο = o
• ύποπτος = EE-pop-tos
• περιμένει = pe-ri-ME-ni

So the whole sentence sounds roughly like:

o EE-pop-tos pe-ri-ME-ni

A few notes:

• υ here sounds like ee
• the stress in ύποπτος is on the first syllable
• the stress in περιμένει is on μέ

The accent mark shows which syllable is stressed.

So:

• ύποπτος → stress on ύ
• περιμένει → stress on μέ

Stress matters in Greek pronunciation, so it is important to learn words together with their accents.

Because it is at the beginning of the sentence, so it is capitalized.

Normally, in the middle of a sentence, it would be written ο.

Compare:

• Ο ύποπτος περιμένει.
• Βλέπω τον ύποπτο.

It is in the nominative case, because it is the subject of the sentence.

You can tell from:

• the article Ο, which is nominative masculine singular
• the role in the sentence: the suspect is the one doing the action

If it were the direct object, you would usually see:

• τον ύποπτο

For example:

• Βλέπω τον ύποπτο. = I see the suspect.

Yes. Greek word order is more flexible than English word order.

You can say:

• Ο ύποπτος περιμένει.
• Περιμένει ο ύποπτος.

Both mean roughly The suspect is waiting, but the emphasis can change.

Usually:

• Ο ύποπτος περιμένει sounds neutral
• Περιμένει ο ύποπτος may put more focus on the action or sound more contextual

No, not necessarily.

It can stand alone and simply mean:

• is waiting

But it can also take an object:

• Περιμένει το λεωφορείο. = He/She is waiting for the bus.

This is one place where Greek differs from English: Greek often uses περιμένω directly with an object, where English usually says wait for something.

So:

• Greek: Περιμένω τον φίλο μου.
• English: I’m waiting for my friend.

The dictionary form is περιμένω, which means to wait.

Some present-tense forms are:

• περιμένω = I wait / I am waiting
• περιμένεις = you wait / are waiting
• περιμένει = he/she/it waits / is waiting
• περιμένουμε = we wait / are waiting
• περιμένετε = you (plural) wait / are waiting
• περιμένουν(ε) = they wait / are waiting

It is neutral and standard. Nothing in it is especially formal or informal.

Both words are ordinary modern Greek:

• ύποπτος = suspect
• περιμένει = is waiting / waits

So it would fit in normal speech, writing, news-style language, or textbook examples.

Usually, with Ο ύποπτος, the most natural reading is the suspect.

But grammatically, the adjective itself still has the meaning suspicious. Greek often lets context decide whether the adjective is being used:

• descriptively: a suspicious man
• substantively: the suspect

In this sentence, the article and overall structure strongly favor the noun-like meaning the suspect.

Greek normally uses the article with ordinary nouns in full sentences much more regularly than English does.

So in a normal statement:

• Ο ύποπτος περιμένει.

the article is expected.

English can sometimes omit articles in headlines or special styles, but standard Greek prose would normally keep it here.

A good way is to break it into two chunks:

• Ο ύποπτος = the suspect
• περιμένει = is waiting / waits

Then remember the pattern:

• article + noun + verb

So the whole sentence is a very typical Greek structure: The suspect is waiting.
