ליקוי הבנייה התגלה בתקופת האחריות.

ליקוי הבנייה is a construct chain (called סמיכות in Hebrew), which is a very common way to say the construction defect or the defect of the construction.

In a construct chain:

• the first noun usually does not take ה־
• the second noun can carry the definiteness for the whole phrase

So:

• ליקוי בנייה = a construction defect
• ליקוי הבנייה = the construction defect

Even though ליקוי itself has no ה־, the whole phrase is definite because הבנייה is definite.

You can sometimes use של, but the construct form is more natural and more compact here.

Here הבנייה means the construction in the sense of the building work / construction process.

That is different from בניין, which usually means:

• a building as a physical structure
• or in grammar, a verb pattern

So in this sentence:

• ליקוי הבנייה = a defect in the construction work
• not a defect in a building as an object

This is an important distinction for learners, because English often uses building and construction in overlapping ways, while Hebrew separates them more clearly here.

התגלה is the past tense, masculine singular form of the verb להתגלות, which means to be discovered, to be revealed, or to come to light.

So:

• התגלה = was discovered / came to light

It comes from the root ג־ל־ה, related to revealing or uncovering.

This verb is a natural choice when something is found out or becomes known. It is slightly more formal than a very everyday verb like נמצא in some contexts.

Because the subject is ליקוי, and ליקוי is:

• singular
• masculine

So the verb agrees with it:

• ליקוי ... התגלה = The defect ... was discovered

If the subject were feminine singular, you would expect התגלה to change accordingly.
If it were plural, the verb would also change.

Hebrew can often use either subject–verb or verb–subject order, especially in written language.

Here:

• ליקוי הבנייה התגלה sounds natural and somewhat formal
• it presents the construction defect as the topic first

You could also see:

• התגלה ליקוי בנייה
• התגלה ליקוי הבנייה

Those are also possible, but they may shift the emphasis a little. Starting with the noun phrase makes the sentence feel more like a factual statement about that defect.

This is another place where Hebrew uses a construct chain.

Break it down:

• ב־ = in / during
• תקופת = period of ... (construct form of תקופה)
• האחריות = the warranty / the responsibility

So:

• בתקופת האחריות = literally in the period of the warranty
• natural English: during the warranty period

Hebrew often uses ב־ with time expressions to mean in or during, so this is very normal.

Because in a construct chain, the first noun normally does not take the definite article.

So:

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

The definiteness comes from the second noun, האחריות, and it makes the whole phrase definite.

This is exactly the same pattern as:

• ליקוי הבנייה
• תקופת האחריות

Both are construct chains where the first noun has no ה־, but the whole phrase is still definite.

Yes. אחריות can mean:

• responsibility
• liability
• warranty / guarantee

Here, because of the context, it means warranty.

So:

• תקופת האחריות = the warranty period

This is a very common kind of Hebrew word: one word can cover several related meanings, and the context tells you which one is intended.

Yes, it sounds fairly formal or written, especially because of words like:

• ליקוי = defect
• התגלה = was discovered / came to light
• תקופת האחריות = warranty period

In everyday speech, someone might use simpler or more conversational wording depending on the situation. But this sentence is completely natural, especially in:

• legal contexts
• customer service
• real-estate or construction reports
• formal complaints

A simple pronunciation guide is:

li-KUY ha-bni-YA hit-ga-LA be-tku-FAT ha-a-kha-ra-YUT

A few helpful notes:

• ליקוי sounds roughly like lee-KOOY
• הבנייה has stress at the end: ha-bni-YA
• התגלה has stress on the last syllable: hit-ga-LA
• בתקופת has stress on the last syllable: be-tku-FAT
• האחריות has stress near the end: ha-a-kha-ra-YUT

Pronunciation can vary slightly by speaker, but this will be understood well.

Yes. Even if the overall meaning has already been given, it is useful to know that several English words may fit:

• defect
• flaw
• fault

Likewise, התגלה can be rendered as:

• was discovered
• was found
• came to light

The exact English choice depends on tone and context. In a formal construction or legal context, defect is often the best match.
