Αν είχα πάρει ομπρέλα, δεν θα βιαζόμουν στον δρόμο.

It’s an unreal past conditional:

• Αν + past perfect (Αν είχα πάρει…) = a condition that did not happen in the past (If I had taken…).
• θα + imperfect (δεν θα βιαζόμουν…) = the imagined result (I wouldn’t be hurrying / I wouldn’t hurry).

So it corresponds to English If I had…, I would… (often “would be …” for an ongoing situation).

είχα πάρει is the past perfect (pluperfect) of παίρνω. It’s formed as:

• imperfect of έχω: είχα (“I had”)
• • the so‑called perfect/aorist participle: πάρει (“taken”)

So literally it’s like I had taken.

θα is a particle that marks future/conditional meaning depending on context. Here, with a past conditional clause (Αν είχα…), θα expresses a conditional result: would / would be.

So θα here is not “will” in the normal future sense; it functions like would.

βιαζόμουν is imperfect, which presents the action/state as ongoing at that time: I would be in a hurry / I would be hurrying (during the walk/drive).

If you wanted a completed-result meaning like I wouldn’t have hurried (at all), Greek could use a different form, e.g.:

• …δεν θα είχα βιαστεί… (perfective, “I wouldn’t have hurried”)

So the imperfect here adds the nuance of an ongoing rush on the road.

The dictionary form is βιάζομαι, which is mediopassive in form but often active in meaning: I’m in a hurry / I hurry.

βιαζόμουν = 1st person singular, imperfect, mediopassive:

• “I was hurrying / I was in a hurry” With θα, it becomes “I would be hurrying”.

Many common Greek verbs use mediopassive endings without a passive meaning.

In standard Modern Greek, δεν (negation) typically comes before the particle θα:

• δεν θα βιαζόμουν = “I would not be hurrying”

This is the normal order for negating future/conditional constructions.

στον is a contraction of σε + τον:

• σε (“in/on/to/at” depending on context)
• τον (“the”, masculine accusative)

So στον δρόμο literally means in/on the road. Depending on context, it can imply:

• physically “on the road/street”
• “while out on the street / on my way”

Greek often omits the article when talking about something in a general/indefinite way:

• είχα πάρει ομπρέλα ≈ “I had taken an umbrella / I had brought an umbrella”

If you mean a specific umbrella (e.g., my umbrella or the one we mentioned), you can use the article:

• είχα πάρει την ομπρέλα (μου) = “I had taken the umbrella (of mine)”

Both are natural; the difference is specificity.

Yes, and it’s common, but the nuance shifts:

• Αν είχα πάρει… (past perfect) focuses on a missed past action: “If I had taken an umbrella (but I didn’t)…”
• Αν έπαιρνα… (imperfect) can sound more like a general unreal scenario or a less tightly time-anchored past habit/situation: “If I were taking / took an umbrella…”

In many everyday contexts both work; είχα πάρει is clearer for a one-time past “missed opportunity.”

They mean the same thing: “if”.

• αν is the everyday, most common form.
• εάν is more formal or careful style.

Your sentence uses the normal conversational option (Αν).
