Ovo je strujni kabel.

Ovo is the neuter form of this when you are pointing to or identifying something in a general way, especially an object.

Croatian often uses ovo je ... for this is ... when introducing or identifying something:

• Ovo je knjiga. = This is a book.
• Ovo je moj prijatelj. = This is my friend.

Even though kabel is masculine, ovo is still normal here because it refers to this thing here in a general identifying structure.

If you use ovaj, you are directly matching the masculine noun:

• Ovaj kabel je nov. = This cable is new.

So:

• Ovo je strujni kabel. = identifying something
• Ovaj kabel ... = talking directly about this cable

Je means is. It is the 3rd person singular present form of biti = to be.

So the structure is:

• ovo = this
• je = is
• strujni kabel = power cable / electrical cable

Croatian usually needs je here, just like English needs is in This is a power cable.

Strujni is an adjective related to electric current or power.

It comes from struja, which means current, electricity, or electrical power depending on context.

So strujni kabel means something like:

• power cable
• electrical cable
• literally, current-related cable

In everyday English, power cable is often the most natural translation.

Because Croatian normally uses an adjective before a noun in this kind of phrase.

• struja = electricity / current
• strujni = electrical / power-related

So instead of putting two nouns together as English often does, Croatian commonly turns the first idea into an adjective:

• strujni kabel = power cable
• compare English: power cable, where power acts like a modifier

This is a very common pattern in Croatian.

Yes, kabel is masculine.

One clue is that many Croatian masculine nouns in the nominative singular end in a consonant, and kabel ends in -l.

You can also see it from the adjective:

• strujni is the masculine singular nominative form
• if the noun were feminine, you would expect strujna
• if it were neuter, you would expect strujno

So strujni kabel shows that kabel is masculine.

It is in the nominative singular.

This is because the sentence is an identification sentence:

• Ovo je strujni kabel. = This is a power cable.

In Croatian, the noun after je in this type of sentence is commonly in the nominative.

Breakdown:

• strujni = masculine singular nominative
• kabel = masculine singular nominative

A rough English-friendly pronunciation is:

OH-vo yeh STROOY-nee KAH-bel

A few notes:

• j is pronounced like English y
• je sounds roughly like yeh
• struj- contains uj, which sounds a bit like oo-y
• kabel has a clear k, not a soft one

A more careful breakdown:

• Ovo = OH-vo
• je = yeh
• strujni = STROOY-nee
• kabel = KAH-bel

Yes, you often can.

Both can refer to an electrical cable, but the nuance may depend on context:

• strujni kabel often suggests a power cable, a cable carrying electrical current
• električni kabel is a bit broader and can simply mean electrical cable

In many everyday situations, both are understandable. If you specifically mean a cable for power supply, strujni kabel is very natural.

Kabel is the standard and very common word.

You may also hear kabl in some varieties, but kabel is the standard form learners should use.

So for most purposes, kabel is the safest choice.

Yes, Croatian word order is more flexible than English, but Ovo je strujni kabel is the most neutral and natural order here.

You might change word order for emphasis, but beginners should stick with:

• Ovo je strujni kabel.

That is the clearest default pattern for This is ...

Normally, no.

Je strujni kabel by itself sounds incomplete in standard Croatian. You usually need the subject or pointing word here:

• Ovo je strujni kabel. = This is a power cable.
• To je strujni kabel. = That is a power cable. / That is a power cable there.

If you are speaking casually, Croatian sometimes omits parts that are obvious from context, but as a learner you should keep ovo je in this sentence type.
