הצעת המחיר המפורטת כוללת את תקופת האחריות.

הצעת המחיר is a construct phrase (called סמיכות in Hebrew), meaning the price quote or more literally the proposal of the price.

The first noun, הצעת, is the construct form of הצעה (proposal / offer / quote).
The second noun, המחיר, means the price.

So:

• הצעה = a proposal / an offer
• הצעת מחיר = a price quote
• הצעת המחיר = the price quote

Hebrew often prefers this compact noun+noun structure where English might use of or a compound noun.

In a construct phrase, the definiteness of the whole phrase is usually determined by the second noun.

So in:

• הצעת מחיר = a price quote
• הצעת המחיר = the price quote

Even though the first word הצעת does not get ה־, the whole phrase becomes definite because המחיר is definite.

This is a very common Hebrew pattern.

Because it describes הצעת המחיר, and the head noun of that phrase is הצעת / הצעה, which is feminine singular.

• הצעה = feminine singular
• so the adjective must also be feminine singular
• therefore: מפורטת = detailed

Since the noun phrase is definite, the adjective is also definite:

• הצעת המחיר המפורטת = the detailed price quote

So the adjective agrees with the noun it modifies in:

• gender
• number
• definiteness

It describes הצעת — the quote/proposal, not the price.

That is why it is feminine:

• הצעה is feminine
• מחיר is masculine

If the adjective were describing מחיר, you would expect a masculine form such as מפורט.

So:

• הצעת המחיר המפורטת = the detailed price quote
• not the quote of the detailed price

In Hebrew, an adjective that modifies a construct phrase usually comes after the entire phrase, not in the middle.

So:

• הצעת המחיר המפורטת = the detailed price quote

Not:

• הצעת המפורטת המחיר ✘

This is standard Hebrew word order.

A useful rule:

• first build the noun phrase
• then place the adjective after it

כוללת means includes.

It comes from the verb לכלול = to include.

Here it is in the:

• present tense
• feminine singular form

Why feminine singular? Because the subject is הצעת המחיר המפורטת, whose main noun is הצעה, a feminine singular noun.

Compare:

• ההסכם כולל = the agreement includes (masculine singular)
• ההצעה כוללת = the proposal includes (feminine singular)

Because in Hebrew, the present tense often works like the English simple present for facts, descriptions, and general statements.

So:

• הצעת המחיר המפורטת כוללת... = The detailed price quote includes...

This is a normal way to describe what a document, offer, contract, or list contains.

את is the marker of a definite direct object.

It does not mean with here.
It marks the thing that the verb acts on.

In this sentence:

• כוללת = includes
• את תקופת האחריות = the warranty period

Hebrew uses את before a direct object when that object is definite.

So:

• כוללת תקופה = includes a period
• כוללת את התקופה = includes the period

Here the object is definite because תקופת האחריות means the warranty period.

Again, this is a construct phrase.

• תקופה = period
• תקופת = period of ...
• אחריות = warranty / responsibility
• האחריות = the warranty

So:

• תקופת אחריות = a warranty period
• תקופת האחריות = the warranty period

Hebrew often prefers this compact structure instead of using של.

For the same reason as in הצעת המחיר: in a construct phrase, definiteness is usually shown on the second noun.

So:

• תקופת אחריות = a warranty period
• תקופת האחריות = the warranty period

The first noun תקופת stays without ה־, but the whole phrase is definite because האחריות is definite.

Yes, it refers to a specific warranty — the one associated with the product, service, or quote being discussed.

In business or legal Hebrew, phrases like this often use the definite form because the context makes it clear which warranty is meant.

So תקופת האחריות is naturally understood as:

• the warranty period
• not just a warranty period

The sentence is:

הצעת המחיר המפורטת כוללת את תקופת האחריות.

Its structure is:

• Subject: הצעת המחיר המפורטת
  = the detailed price quote
• Verb: כוללת
  = includes
• Direct object: את תקופת האחריות
  = the warranty period

So it follows a very common Hebrew pattern:

Subject + Verb + Direct Object

Only roughly.

A very literal breakdown would be:

• הצעת = proposal/quote of
• המחיר = the price
• המפורטת = the detailed
• כוללת = includes
• את = definite direct object marker
• תקופת = period of
• האחריות = the warranty

But natural English would be:

• The detailed price quote includes the warranty period.

So Hebrew and English match in overall meaning, but not perfectly word-for-word.

A simple pronunciation guide is:

hatsa'at hamekhir hameforétet kolelet et tkufat ha'achrayút

A few notes:

• הצעת sounds roughly like hatsa-AT
• מחיר sounds like mekh-EER
• המפורטת sounds like hame-fo-RE-tet
• כוללת sounds like ko-LE-let
• תקופת sounds like tku-FAT
• האחריות sounds like ha-ach-ra-YUT

Pronunciation varies somewhat by speaker, but this is a good general guide.

Sometimes yes, but here the construct form is the most natural and standard.

For example:

• הצעת המחיר is much more natural than ההצעה של המחיר
• תקופת האחריות is much more natural than התקופה של האחריות

Using של here would sound less idiomatic, and in some cases awkward.

In formal, business, and written Hebrew, construct phrases like these are especially common.
