החקירה צריכה עוד ראיות.

• החקירה = the investigation
• צריכה = needs / is in need of
• עוד = more / additional
• ראיות = evidence / pieces of evidence

So the full sentence means something like The investigation needs more evidence.

Because החקירה is a feminine singular noun.

In Hebrew, words like צריך / צריכה / צריכים / צריכות agree with the subject in gender and number:

• הוא צריך = he needs
• היא צריכה = she needs
• הם צריכים = they (masc./mixed) need
• הן צריכות = they (fem.) need

Since חקירה is feminine singular, the correct form is צריכה.

Not exactly in the same way as the English verb need.

In modern Hebrew, צריך / צריכה often behaves like an adjective or participle meaning in need of / needing, but in everyday usage it is commonly translated as need.

So החקירה צריכה עוד ראיות literally feels a bit like:

• The investigation is needing more evidence
• or The investigation is in need of more evidence

But in natural English, you simply say The investigation needs more evidence.

The prefix ה־ is the Hebrew definite article, meaning the.

So:

• חקירה = an investigation / investigation
• החקירה = the investigation

Hebrew usually attaches the directly to the noun instead of writing it as a separate word.

Here עוד means more or additional.

So:

• עוד ראיות = more evidence / additional evidence

Be careful, because עוד can also mean still or yet in other contexts. Its exact meaning depends on the sentence.

Examples:

• אני עוד מחכה = I am still waiting
• אני צריך עוד זמן = I need more time

In your sentence, it clearly means more.

That is a very common and important question.

In Hebrew, ראיה means a piece of evidence / proof, and the plural ראיות is very natural. Hebrew often treats this idea as something countable.

So:

• ראיה = a piece of evidence
• ראיות = pieces of evidence / evidence

Even though English often prefers uncountable evidence, Hebrew commonly uses the plural ראיות where English would still say just evidence.

So עוד ראיות is perfectly normal Hebrew.

Because את is only used before a definite direct object.

Here, עוד ראיות is indefinite:

• not the evidence
• just more evidence

So you do not use את.

Compare:

• החקירה צריכה עוד ראיות = The investigation needs more evidence
• החקירה צריכה את הראיות האלה = The investigation needs these pieces of evidence

In the second sentence, את appears because הראיות האלה is definite.

Yes. This is a very normal and natural word order:

• החקירה = subject
• צריכה = predicate
• עוד ראיות = what is needed

So the structure is basically:

The investigation + needs + more evidence

Hebrew can sometimes vary word order for emphasis, but this version is straightforward and standard.

Yes. That is also correct, and it means nearly the same thing.

• החקירה צריכה עוד ראיות = The investigation needs more evidence
• החקירה זקוקה לעוד ראיות = The investigation is in need of more evidence

A small grammar note:

• צריך / צריכה is followed directly by the noun
• זקוק / זקוקה usually takes ל־

So:

• צריכה עוד ראיות
• זקוקה לעוד ראיות

Both are good, but צריכה is often simpler and very common.

A simple pronunciation guide is:

ha-khi-RA tsi-kha OD re-a-YOT

A few notes:

• חקירה has the stress on the last syllable: ra
• צריכה is pronounced tsri-kha or tsi-kha, depending on accent and speaking speed
• ראיות has stress on the last syllable: yot

A smoother full pronunciation would be:

ha-khki-RA tsri-KHA od re-a-YOT
