Η παγίδα είναι εδώ.

A natural pronunciation is roughly ee pa-YEE-tha EE-ne e-THO.

A few helpful notes:

• Η sounds like ee
• In παγίδα, the γ before ί is a soft sound, somewhat like y in yes
• The δ sound in παγίδα and εδώ is like th in this, not like th in thin
• The stress falls on -γί-, εί-, and -δώ

Η is the feminine singular definite article, so here it means the.

Greek articles change for gender, number, and case. Since παγίδα is a feminine singular noun, the article must also be feminine singular: η.

At the beginning of the sentence it is written with a capital letter: Η instead of η.

No. Even though Η may look like the English letter H, in Greek it is a completely different letter.

Here, Η is pronounced ee. It does not make an h sound.

So Η παγίδα is pronounced more like ee pa-YEE-tha, not h pa-YEE-tha.

Because grammatical gender in Greek is a property of the noun itself. Παγίδα happens to be a feminine noun.

That does not mean the object is biologically female. It just means the word belongs to the feminine gender class, so it takes feminine forms such as:

• η παγίδα = the trap
• adjectives describing it would also appear in feminine forms

This is something you usually learn together with the noun: not just παγίδα, but η παγίδα.

Είναι is the present tense form of είμαι, which means to be.

In this sentence, είναι means is:

• Η παγίδα είναι εδώ = The trap is here

A useful thing to know is that είναι is also used for are in the third person plural:

• Οι παγίδες είναι εδώ = The traps are here

Εδώ is an adverb, and it means here.

It tells you the location of something. In this sentence, it tells you where the trap is:

• Η παγίδα είναι εδώ = the trap is here

It does not change form for gender or number.

That is the most neutral and natural word order here: subject + verb + adverb

• Η παγίδα = subject
• είναι = verb
• εδώ = adverb of place

Greek word order is more flexible than English, so other orders are possible, such as Εδώ είναι η παγίδα, but they can change the emphasis. The version you have is the plain, straightforward way to say it.

The accent marks show which syllable is stressed.

So:

• παγίδα → stress on γί
• είναι → stress on εί
• εδώ → stress on δώ

Stress matters in Greek pronunciation, so these marks are important and should be learned as part of the word.

Yes. Παγίδα can mean a literal trap, but it can also be used figuratively for a trap, pitfall, or set-up.

So depending on context, Η παγίδα είναι εδώ could mean:

• a real trap is here
• the danger or hidden problem is here
• this is where the catch is

The exact interpretation depends on the wider context.
