Hợp đồng thuê nhà; hóa đơn tiền điện.

Because Hợp đồng thuê nhà and hóa đơn tiền điện are both noun phrases, not complete sentences.

• Hợp đồng thuê nhà = house rental contract / lease agreement
• hóa đơn tiền điện = electricity bill

Vietnamese often uses short noun phrases like this in lists, forms, labels, or document checklists.

It breaks down like this:

• hợp đồng = contract, agreement
• thuê = to rent
• nhà = house, home

So hợp đồng thuê nhà literally means something like contract for renting a house/home.

In natural English, this is usually rental contract, lease, or lease agreement.

In Vietnamese, the main noun usually comes first, and words after it often describe or specify it.

So:

• hợp đồng = the main noun: contract
• thuê nhà = what kind of contract: a house-renting contract

This is a very common Vietnamese pattern:

• hóa đơn tiền điện = bill for electricity
• vé máy bay = airplane ticket
• cửa hàng quần áo = clothing store

English often uses of, for, or noun-noun combinations, but Vietnamese usually just places the words next to each other.

It breaks down like this:

• hóa đơn = bill, invoice
• tiền điện = electricity money / electricity charge

So hóa đơn tiền điện literally means bill for electricity charges, or more naturally, electricity bill.

Because tiền means money or payment, and adding it shows that we are talking about the cost/charge for electricity, not electricity itself.

Compare:

• điện = electricity
• tiền điện = electricity payment / electricity charges
• hóa đơn tiền điện = electricity bill

This pattern is very common:

• tiền nhà = rent / housing payment
• tiền nước = water bill / water charge
• tiền điện thoại = phone charges / phone bill

Yes. Nhà is broader than English house. Depending on context, it can mean:

• house
• home
• residence

So thuê nhà can mean rent a house, but in some contexts it may feel closer to rent a place to live. In English, rental agreement or lease agreement is often the most natural translation.

No extra word is required. Vietnamese often forms noun phrases by simply placing words together.

For example:

• hợp đồng thuê nhà does not need cho
• hóa đơn tiền điện does not need của

A learner might expect something like bill of electricity or contract for renting a house, but Vietnamese usually expresses this more compactly.

That said, in other contexts, words like cho, về, or của can appear, but they are not needed in these standard expressions.

The semicolon simply separates two items:

• Hợp đồng thuê nhà
• hóa đơn tiền điện

So this looks like a list, perhaps on a form, checklist, or set of required documents. It does not create a special grammatical relationship between the two phrases.

Because hóa đơn usually means bill or invoice, not a proof of payment.

A useful distinction is:

• hóa đơn = bill / invoice
• biên lai = receipt

So hóa đơn tiền điện is the bill you receive for electricity charges. If you want to emphasize proof that you already paid, biên lai tiền điện would be closer to electricity payment receipt.

A rough pronunciation guide:

• Hợp đồng thuê nhà ≈ hup downg tway nya
• hóa đơn tiền điện ≈ hwa dun tyen dyen

A few notes:

• đ is like English d
• nh sounds somewhat like the ny in canyon
• th in thuê is an aspirated t, not English th
• điện has a different vowel quality from English dee-en; try to keep it as one Vietnamese syllable with the proper tone

If you are studying pronunciation, the tones matter a lot here, especially in:

• hợp
• đồng
• thuê
• hóa
• tiền
• điện

Yes. Very often.

In Vietnamese, short noun phrases are commonly used:

• on forms
• in application checklists
• as document labels
• in messages listing required paperwork

For example, a landlord or office might list:

• Hợp đồng thuê nhà
• Hóa đơn tiền điện
• CMND/CCCD
• Sổ hộ khẩu

So even without a full sentence, the meaning is completely natural in context.

Yes, that is a good idea.

Both are common document-related phrases:

• hợp đồng thuê nhà = rental contract / lease agreement
• hóa đơn tiền điện = electricity bill

Memorizing them as whole chunks will help, but it is also useful to notice the smaller building blocks:

• hợp đồng = contract
• thuê = rent
• nhà = house/home
• hóa đơn = bill/invoice
• tiền = money/payment
• điện = electricity

That way, you can understand similar phrases more easily.
