انا مليت الاستمارة، بس نسيت امضي عليها.

A simple pronunciation guide is:

ana maleet il-istimāra, bas neseet emDi ʿalēha

A few notes:

• أنا = ana
• مليت = maleet
• الاستمارة = il-istimāra or el-istimāra
• بس = bas
• نسيت = neseet
• أمضي = emDi
• عليها = ʿalēha

Two sounds English speakers often notice:

• ʿ in ʿalēha is the letter ع, a throat sound with no exact English equivalent.
• D in emDi represents ض, a heavier, emphatic d sound.

Yes, you can leave it out.

Arabic verbs already show the subject, and مليت and نسيت both already mean I filled and I forgot. So:

• أنا مليت الاستمارة، بس نسيت امضي عليها
• مليت الاستمارة، بس نسيت امضي عليها

Both are natural.

Including أنا can add clarity, contrast, or emphasis, but it is not required.

No. This exact sentence works for both men and women.

In Egyptian Arabic, first-person singular verbs do not change for gender. So a man and a woman both say:

أنا مليت الاستمارة، بس نسيت امضي عليها

مليت means I filled.

With forms and paperwork, Arabic usually just uses the verb fill without needing a separate word like English out. So:

• مليت الاستمارة = literally I filled the form
• natural English meaning: I filled out the form

So nothing is missing in Arabic; it is just expressed differently.

Yes.

It is the Egyptian Arabic form of the same verb root meaning to fill. In Modern Standard Arabic you would say ملأت, while in Egyptian speech the form is commonly مليت.

This is a very common kind of difference between Standard Arabic and Egyptian Arabic: same basic root, but a different spoken pattern.

الـ means the, so الاستمارة means the form.

Here, the speaker is talking about a specific form, not just any form in general. So الاستمارة is the natural choice.

If you wanted to say a form, you would usually say something like:

استمارة

depending on the context.

Here بس means but.

So it connects the two parts of the sentence:

• I filled the form
• but I forgot to sign it

In Egyptian Arabic, بس can also mean only, just, or enough, depending on context. But in this sentence it clearly means but.

Because Arabic does not use an infinitive in the same way English does.

In English, you say:

• I forgot to sign

In Egyptian Arabic, after verbs like forgot, want, can, need, etc., you normally use another conjugated verb:

• نسيت امضي = literally something like I forgot I-sign

This is completely normal Arabic structure.

You see the same pattern in many everyday phrases:

• عايز أروح = I want to go
• لازم أكتب = I have to write
• نسيت امضي = I forgot to sign

أمضي means I sign or, in this context, to sign.

It is a very common verb for signing documents, especially in formal or administrative contexts.

Another very common Egyptian verb is:

أوقّع

So you may also hear:

نسيت أوقّع عليها

That is also natural and very common. In many everyday situations, أوقّع may sound a bit more colloquial, while أمضي can sound slightly more formal.

Because Arabic often says sign on it, not just sign it.

So:

• امضي عليها
• literally: sign on it

This is the normal pattern with documents, forms, papers, contracts, and similar things.

So عليها is not extra or strange; it is the expected Arabic structure.

Because الاستمارة is grammatically feminine.

The attached pronoun must match the noun it refers to:

• عليها = on it for a feminine noun
• عليه = on it for a masculine noun

Since استمارة is feminine, the sentence uses عليها.

For comparison:

• نسيت امضي على العقد = I forgot to sign the contract
• نسيت امضي عليه = I forgot to sign it

Here العقد is masculine, so you get عليه.

Yes, it is natural.

A very common everyday version would be:

مليت الاستمارة، بس نسيت أوقّع عليها

And an even more casual version might drop أنا:

مليت الاستمارة، بس نسيت أوقّع عليها

So the original sentence is good, and there are also small everyday alternatives depending on the speaker and situation.
