Ο συνεργάτης μου με βοήθησε να τελειώσω την αναφορά.

Ο is the masculine singular definite article, meaning the.

In Ο συνεργάτης μου, it agrees with συνεργάτης:

• ο = masculine singular nominative the
• συνεργάτης = colleague / associate / partner

So Ο συνεργάτης μου means my colleague or more literally the colleague of mine.

Greek articles change form depending on gender, number, and case, so you cannot always use the same word for the.

συνεργάτης usually means colleague, associate, collaborator, or sometimes partner, depending on context.

In a workplace sentence like this, the most natural meaning is usually colleague or coworker.

Grammatically:

• it is masculine singular
• here it is in the nominative, because it is the subject of the sentence

Its stress is on the second-to-last syllable: συ-νερ-ΓΑ-της.

In Modern Greek, the unstressed possessive pronoun μου usually comes after the noun.

So:

• ο συνεργάτης μου = my colleague
• literally: the colleague my

This is normal Greek word order for possession.

Other examples:

• το σπίτι μου = my house
• η αδερφή μου = my sister

Putting possession before the noun is not the normal pattern in Greek.

They are different pronouns with different jobs:

• μου = my / of me here, showing possession

  • ο συνεργάτης μου = my colleague

• με = me, the direct object of the verb βοήθησε

  • με βοήθησε = helped me

So:

• μου answers whose colleague?
• με answers helped whom?

This distinction is very important in Greek.

In standard Modern Greek, short object pronouns like με, σε, τον, την, μας usually come before the verb.

So:

• με βοήθησε = he/she helped me

This is the normal placement for unstressed object pronouns.

You may sometimes hear different placement in speech for emphasis or in special structures, but for learners, the rule to remember is:

• clitic object pronoun + verb
• με βοήθησε
• σε είδα
• τον ξέρω

βοήθησε is the aorist form, third person singular, of βοηθάω / βοηθώ.

Here it means:

• he/she helped

Why the aorist? Because it presents the action as a completed event in the past.

So:

• με βοήθησε = he/she helped me
• not was helping me or used to help me

If you wanted an ongoing or habitual meaning, Greek would use a different past form.

Modern Greek does not normally use an infinitive the way English does.

Instead of saying:

• helped me to finish

Greek says something like:

• helped me that I finish

That structure uses να + a finite verb:

• να τελειώσω

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

So after many verbs where English uses an infinitive, Greek often uses:

• να + verb

Examples:

• Θέλω να πάω. = I want to go.
• Μπορώ να έρθω. = I can come.
• Με βοήθησε να τελειώσω... = He helped me finish...

τελειώσω is the first person singular aorist subjunctive form of τελειώνω.

In this sentence it means:

• (that) I finish
• or more naturally in English: to finish

Why this form? Because after να, Greek uses subjunctive-type forms, and here the aorist version is used because the idea is completing the report.

So να τελειώσω suggests:

• finishing it as a whole
• bringing it to completion

This is about the difference between perfective and imperfective forms.

• να τελειώσω = to finish / complete
• να τελειώνω = to be finishing / finish repeatedly / be in the process of finishing, depending on context

In this sentence, the idea is clearly:

• my colleague helped me complete the report

So Greek uses the aorist/perfective form:

• να τελειώσω

If the sentence were about an ongoing process rather than completion, a different form might be used.

την αναφορά is the direct object of τελειώσω.

Breakdown:

• την = feminine singular accusative the
• αναφορά = report

Because αναφορά is a feminine noun and it is the object of the verb, Greek uses:

• την αναφορά

Compare:

• η αναφορά = the report as subject
• την αναφορά = the report as object

This is a case difference:

• η = nominative
• την = accusative

Here is the case breakdown:

• Ο συνεργάτης μου → nominative
  because it is the subject

• με → accusative object pronoun
  because it is the person being helped

• την αναφορά → accusative
  because it is the thing being finished

So the sentence structure is basically:

• subject
  • object pronoun
    • verb
      • να-clause

Yes. The verb ending in τελειώσω shows first person singular, so the understood subject is I.

That means:

• με βοήθησε να τελειώσω την αναφορά = he/she helped me finish the report literally, = he/she helped me so that I finish the report

So even though I is not written as a separate word, it is built into the verb form τελειώσω.

Greek often leaves subject pronouns out because the verb ending already tells you the person.

Yes. Greek word order is more flexible than English, because case endings and verb forms show grammatical roles.

The neutral order here is:

• Ο συνεργάτης μου με βοήθησε να τελειώσω την αναφορά.

But Greek can move things around for emphasis, for example:

• Με βοήθησε ο συνεργάτης μου να τελειώσω την αναφορά.
• Την αναφορά με βοήθησε να τελειώσω ο συνεργάτης μου.

These may sound more marked or emphasize different parts of the sentence.

For learners, the original version is a very natural and safe word order.

When βοηθάω means help someone do something, Greek normally uses:

• βοηθάω + object + να + verb

So:

• Με βοήθησε να τελειώσω...

That is the standard pattern.

You should think of it as:

• help + someone + να + action

Examples:

• Με βοήθησε να καταλάβω. = He helped me understand.
• Τον βοήθησα να φύγει. = I helped him leave.

You would change the article and noun to the feminine form:

• Η συνεργάτιδά μου με βοήθησε να τελειώσω την αναφορά.

Changes:

• Ο → Η
• συνεργάτης → συνεργάτιδα or συνεργάτιδά μου in this phrasing

Everything else can stay the same.

So the meaning becomes:

• My female colleague helped me finish the report.

A rough pronunciation guide is:

O sy-ner-GA-tis mou me vo-I-thi-se na te-li-O-so tin a-na-fo-RA

A few stress points:

• συνεργάτης → -ΓΑ-
• βοήθησε → -ΟΗ-
• τελειώσω → -Ω-
• αναφορά → -ΡΑ

Also note:

• η and ι often sound like ee
• αι often sounds like e
• οι often sounds like ee

So Greek spelling is not random, but several different letter combinations can sound similar.

Yes. αναφορά can mean report, but depending on context it can also mean:

• reference
• mention
• referral
• in some formal or technical contexts, other related meanings

In this sentence, because of finish the report, the natural meaning is clearly a written or work-related report.

So this is a good example of how vocabulary meaning often depends on context.
