Η υποψία μου δεν έφυγε όταν άκουσα την απάντησή του.

Η is the feminine singular definite article, meaning the.

The noun υποψία is feminine, so in the nominative singular it takes η:

• η υποψία = the suspicion

In this sentence, η υποψία μου is the subject, so the nominative form is used.

Greek often uses the definite article more regularly than English does, so where English might say my suspicion, Greek naturally says the suspicion of me / my suspicion = η υποψία μου.

In Greek, possessive weak pronouns usually come after the noun:

• η υποψία μου = my suspicion
• η απάντησή του = his answer

So μου here means my, but grammatically it is the weak genitive form of I/me.

This word order is completely normal in Greek:

• το βιβλίο μου = my book
• η φίλη μου = my friend

Υποψία means suspicion.

In this sentence it refers to a feeling of doubt or distrust. So η υποψία μου δεν έφυγε means something like:

• my suspicion did not go away
• I still had my suspicions

Greek often uses nouns like this where English might prefer a more verbal expression.

Δεν is the basic negation word used with indicative verbs in Greek. It means not.

So:

• έφυγε = it went away / it left
• δεν έφυγε = it did not go away / it did not leave

You use δεν before verbs in ordinary negative statements.

Yes, έφυγε literally means left or went away, from the verb φεύγω.

But Greek often uses φεύγω in expressions where English says something like:

• go away
• disappear
• pass
• leave

So η υποψία μου δεν έφυγε literally means my suspicion did not leave, but naturally in English it means:

• my suspicion didn’t go away
• I was still suspicious

This is a very normal Greek way to express that a feeling or impression remained.

Έφυγε is the aorist form of φεύγω.

The Greek aorist usually presents an action as a single whole event. Here, δεν έφυγε means that the suspicion did not disappear at that point.

So the sentence is not describing an ongoing process like was leaving. It presents the event as a complete possibility that simply did not happen:

• it didn’t go away

That is why the aorist is natural here.

Άκουσα is also aorist, from ακούω, and it means I heard.

The aorist is used because the sentence refers to a specific completed moment:

• when I heard his answer

If you used άκουγα, that would be imperfect and would mean something more like:

• while I was listening
• used to listen
• was hearing

But here the idea is a single event that happened once, so άκουσα is the right choice.

Here όταν means when, referring to a specific moment in the past:

• όταν άκουσα την απάντησή του = when I heard his answer

Όταν can sometimes also mean whenever, depending on context, but in this sentence the aorist άκουσα makes it clear that we are talking about one completed past event.

So the meaning is:

• at the moment I heard his answer, my suspicion did not disappear

Την απάντησή του is in the accusative, because it is the direct object of άκουσα:

• άκουσα τι; → την απάντησή του
• I heard what? → his answer

The basic noun is η απάντηση:

• nominative: η απάντηση
• accusative: την απάντηση

Because the weak possessive του follows, Greek often writes the noun with an extra accent:

• την απάντησή του

This helps show the correct stress pattern in connected speech.

The normal accusative form is την απάντηση.

When a weak pronoun like μου, σου, του, της follows, Greek often adds a second accent to the preceding word if needed:

• η απάντησή του
• η φωνή μου
• το όνομά σου

This is not a different word or case. It is mainly about pronunciation and stress. Greek spelling reflects the fact that these little pronouns are unstressed and attach closely to the previous word.

So:

• την απάντηση = the answer
• την απάντησή του = his answer

Just like μου in η υποψία μου, του is a weak possessive pronoun and normally comes after the noun:

• η απάντησή του = his answer

This is the standard Greek pattern:

• το σπίτι του = his house
• η μητέρα της = her mother
• οι φίλοι μου = my friends

So Greek possession often looks like:

• the answer his rather than English his answer

The basic structure is:

• Η υποψία μου = subject
• δεν έφυγε = verb
• όταν άκουσα την απάντησή του = time clause

So literally:

• My suspicion did not go away when I heard his answer.

This word order is very natural in Greek. Greek is more flexible than English, but this version is neutral and straightforward.

Yes. A very literal translation is:

• My suspicion did not go away when I heard his answer.

But more natural English could also be:

• Hearing his answer did nothing to ease my suspicions.
• My suspicions remained after I heard his answer.
• I was still suspicious after hearing his answer.

The Greek sentence uses singular η υποψία μου, but English often prefers plural my suspicions in this kind of context. Both are possible depending on style.
