דווחי מיד על גניבת הזהות.

דווחי is the imperative form of לדווח (to report), and it is addressed to one female.

So grammatically it means something like Report! said to a woman or girl.

Related forms:

• דווח — to one male
• דווחי — to one female
• דווחו — to more than one person

Because Hebrew verbs change according to the gender and number of the person being addressed.

English says report! no matter who you are talking to, but Hebrew distinguishes:

• דווח — say it to one man
• דווחי — say it to one woman
• דווחו — say it to a group

So this sentence is specifically directed at a female singular addressee.

In Hebrew, imperative forms already include the idea of you.

So דווחי already means you (feminine singular), report. Because of that, Hebrew normally does not need to add את.

If a pronoun were added, it would usually sound emphatic or contrastive rather than neutral.

Yes. This is perfectly normal, especially in:

• instructions
• warnings
• official notices
• app or website interfaces

That said, in everyday spoken Hebrew, people often use a future tense form instead of the classical imperative. So alongside דווחי מיד, you may also hear:

• תדווחי מיד

Both are understandable. The imperative version often sounds a bit more direct, instructional, or formal.

After לדווח, Hebrew usually uses the preposition על, meaning about / on / regarding.

So:

• לדווח על משהו = to report something / to report about something

This is just the normal pattern of the verb. English says report identity theft, but Hebrew prefers report about identity theft with על.

Because גניבת הזהות is not the direct object here.

The verb pattern is:

• לדווח על...

Since the noun phrase comes after the preposition על, it does not take את.

Compare:

• ראיתי את האיש — I saw the man
  Here את appears because the man is a direct object.
• דיווחתי על גניבת הזהות — I reported the identity theft
  Here there is no את, because the phrase is introduced by על.

גניבת is the construct form of גניבה (theft).

Hebrew often links two nouns together in a structure called the construct state. In this pattern, the first noun changes form and connects to the second:

• גניבה — theft
• גניבת זהות — identity theft / theft of identity

So גניבת means the theft of... and must be followed by another noun.

Because in a Hebrew construct chain, the whole phrase gets its definiteness from the second noun.

So:

• גניבת זהות = identity theft / theft of identity (indefinite)
• גניבת הזהות = the identity theft / the theft of the identity (definite)

Even though גניבת itself does not have ה־, the entire expression is definite because הזהות is definite.

That is why Hebrew says:

• גניבת הזהות

and not:

• הגניבת הזהות

Because Hebrew commonly uses a noun + noun construct where English often uses a noun as an adjective-like modifier.

So English:

• identity theft

Hebrew:

• גניבת זהות
• literally, theft of identity

That is a very normal Hebrew way to express this kind of idea.

That word order is very natural in Hebrew.

• דווחי מיד = Report immediately

Putting מיד after the imperative makes the command sound direct and standard. Hebrew word order is somewhat flexible, so other arrangements are possible for emphasis, but verb + מיד is one of the most common patterns.

In other words, דווחי מיד sounds exactly like the kind of instruction you would expect in a warning or official message.
