يهدر الجهاز المنزلي الطاقة.

Arabic often uses verb–subject–object order, especially in straightforward statements.

So:

• يهدر = wastes
• الجهاز المنزلي = the household device / home appliance
• الطاقة = the energy

This makes the sentence a normal VSO sentence in Arabic.

You could also say:

• الجهاز المنزلي يهدر الطاقة.

That is also correct, but it shifts the feel slightly toward the household device as the topic.

يهدر is a present-tense / imperfect verb, third person masculine singular.

It means:

• he wastes
• it wastes

In this sentence, it means it wastes, because the subject is الجهاز (device), which is grammatically masculine singular.

A fully vocalized form would usually be:

• يُهْدِرُ

So the sentence could be written fully as:

• يُهْدِرُ الجِهَازُ المَنْزِلِيُّ الطَّاقَةَ

Because the subject الجهاز is:

• masculine
• singular

In Arabic, the verb agrees with the subject in gender, and in normal verb-initial sentences it appears in the singular form when the subject is singular.

So:

• الجهاز = masculine singular
• therefore يهدر = masculine singular verb

If the subject were feminine singular, you would expect تهدر instead.

الجهاز means device, machine, or sometimes appliance, depending on context.

المنزلي is an adjective meaning domestic, household, or home-.

Together, الجهاز المنزلي means something like:

• the household device
• the domestic appliance
• the home appliance

In natural English, home appliance is often the smoothest translation.

Because المنزلي is an adjective describing الجهاز, and Arabic adjectives usually match the noun they describe in:

• definiteness
• gender
• number
• case

Since الجهاز is definite because of الـ (the device), the adjective must also be definite:

• الجهاز = the device
• المنزلي = the household/domestic

So:

• الجهاز المنزلي = the household device

If the noun were indefinite, the adjective would also be indefinite:

• جهاز منزلي = a household device

الطاقة means the energy. In Arabic, a direct object can be definite or indefinite, depending on meaning.

Using الطاقة here can suggest energy in a general or known sense, such as:

• energy as a concept
• the energy being consumed
• electrical power

Arabic often uses the definite article in places where English may simply say energy without stressing the.

So يهدر الجهاز المنزلي الطاقة is a natural way to say that the appliance wastes energy.

The sentence breaks down like this:

• يهدر = verb
• الجهاز = subject
• المنزلي = adjective describing the subject
• الطاقة = direct object

So the structure is:

• Verb: wastes
• Subject: the household device
• Object: the energy

If you include full case endings:

• يُهْدِرُ = verb
• الجِهَازُ = subject in the nominative
• المَنْزِلِيُّ = adjective matching the subject
• الطَّاقَةَ = direct object in the accusative

A careful fully vocalized pronunciation is:

• yuhdiru al-jihāzu al-manziliyyu al-ṭāqata

A few helpful notes:

• ج in Modern Standard Arabic is often taught as j as in jam
• ط is an emphatic t
• المنزلي ends with a doubled y sound in full pronunciation: -liyyu
• ة at the end of الطاقة is pronounced -a here because the word is read in context with case ending: al-ṭāqata

In pause, many speakers would simplify the ending and say something closer to:

• yuhdir al-jihāz al-manzilī al-ṭāqa

Yes. المنزلي comes from منزل (house, home) and is a nisba adjective, a common Arabic way of making adjectives meaning:

• related to
• belonging to
• associated with

So:

• منزل = house / home
• منزلي = home-related / domestic / household

In this sentence, المنزلي means domestic or household, not my home.

That distinction matters because without context, منزلي can sometimes mean my home in other situations, but here المنزلي clearly functions as an adjective because it has الـ and follows الجهاز.

Yes, absolutely.

Both are correct:

• يهدر الجهاز المنزلي الطاقة.
• الجهاز المنزلي يهدر الطاقة.

The first is more typically verbal in style and is very common in MSA.

The second starts with the subject, which can make it feel more like:

• As for the household device, it wastes energy
• or simply a more subject-focused statement

So the difference is mostly about style and emphasis, not basic meaning.

Yes. يهدر comes from the root ه د ر.

In this context, the verb أهدر / يهدر means:

• to waste
• to squander

Learning the root can help you recognize related words such as:

• إهدار = wasting / squandering

So if you later see something like:

• إهدار الطاقة

that means:

• wasting energy

This is a useful pattern in Arabic: once you know the root and the verb pattern, related vocabulary becomes easier to recognize.
