Καρφιτσώνω το πατρόν.

Καρφιτσώνω is 1st person singular, so it means I pin.

It is in the present / non-past imperfective form. In practice, that can mean:

• I am pinning the pattern
• I pin the pattern
• I’m pinning the pattern

The exact English translation depends on context.

Greek often drops subject pronouns when they are not needed, because the verb ending already shows who the subject is.

So:

• Καρφιτσώνω = I pin / I am pinning
• Εγώ καρφιτσώνω = I pin with extra emphasis on I

In a simple sentence like this, Εγώ is usually unnecessary.

It means to pin with pins or to attach using pins.

It comes from καρφίτσα, which means pin. So the verb is built from that noun and means something like:

• I pin
• I fasten with pins

In sewing, this is a very natural verb.

Το is the neuter singular definite article, meaning the.

So:

• το πατρόν = the pattern

The noun πατρόν is treated as neuter, so it takes το.

In this context, πατρόν usually means a sewing pattern or dressmaking pattern.

It is a borrowing from another language and is very common in sewing vocabulary in Greek.

So Καρφιτσώνω το πατρόν would normally be understood as something like:

• I pin the pattern
• more naturally in sewing context: I pin the pattern in place

Yes, it is the direct object of the verb, so functionally it is in the accusative.

However, πατρόν is one of those nouns whose form often does not visibly change between cases in everyday use. The article helps show the grammar:

• το πατρόν = the pattern

In this sentence, you know it is the object because of:

1. the verb meaning, and
2. the article-noun group following the verb.

A rough pronunciation is:

• kar-fi-TSO-no to pa-TRON

A slightly more Greek-like guide:

• kar-fee-TSO-no to pa-TRON

The stress falls on:

• καρφιτσώνω
• πατρόν

It can mean either, depending on context.

Because Καρφιτσώνω is a non-past imperfective form, it can be used for:

• an action happening right now: I’m pinning the pattern
• a habitual / general action: I pin the pattern

Context tells you which one is meant.

Yes. Verb + object is very normal in Greek.

So:

• Καρφιτσώνω το πατρόν = normal and natural

Greek word order is fairly flexible, though, so other orders are possible for emphasis, such as:

• Το πατρόν καρφιτσώνω = It’s the pattern that I’m pinning / emphasis on the pattern

But the original sentence is the most neutral one.

Yes. Very often, especially in sewing context, a speaker might add where the pattern is being pinned:

• Καρφιτσώνω το πατρόν στο ύφασμα. = I pin the pattern to the fabric.

The short sentence Καρφιτσώνω το πατρόν is still perfectly fine if the rest is obvious from context.

The dictionary form is καρφιτσώνω itself.

In Greek, many verbs are listed in the 1st person singular present form, unlike English, where dictionaries usually use the bare infinitive.

So if you look it up, you would look for:

• καρφιτσώνω = to pin / I pin

It is most common in sewing, tailoring, and fashion contexts.

A native speaker will understand it, but it is not a very broad everyday noun like book or house. You are especially likely to hear it when talking about:

• sewing patterns
• cutting fabric
• dressmaking
• tailoring

So in this sentence, the context is very likely sewing or garment-making.
