משיכת המזומן היא לא הוראת קבע.

Because משיכת is the construct form of משיכה.

In Hebrew, when one noun is linked to another in an of relationship, the first noun often changes form. This is called סמיכות.

• משיכה = withdrawal
• משיכת המזומן = withdrawal of the cash / the cash withdrawal

So משיכת here means withdrawal of ..., and the next word completes it.

In a construct chain, definiteness is determined by the last noun.

So:

• משיכת מזומן = a cash withdrawal / withdrawal of cash
• משיכת המזומן = the cash withdrawal / withdrawal of the cash

Even though משיכת itself does not take ה־, the whole phrase becomes definite because המזומן is definite.

This is another construct chain.

• הוראה = instruction / order
• הוראת = instruction/order of ...
• קבע = fixed, permanent, regularity

So הוראת קבע literally means something like a permanent instruction or a standing order.

In banking, it usually refers to a standing order, and sometimes in practical translation it may overlap with direct debit, depending on context.

Hebrew usually does not use a separate present-tense verb for to be in simple nominal sentences.

For example:

• דני מורה = Danny is a teacher

But in sentences like this one, especially with negation, Hebrew very often uses a pronoun such as הוא / היא / הם / הן to make the sentence clearer and more natural:

• משיכת המזומן היא לא הוראת קבע

Here היא functions like a present-tense linking word between the subject and the predicate.

A more formal alternative is:

• משיכת המזומן אינה הוראת קבע

No. It refers to the whole subject phrase, whose head noun is משיכה.

That is very important in Hebrew: agreement is based on the main noun of the phrase, not just the nearest noun.

In משיכת המזומן:

• head noun = משיכה = feminine singular
• therefore the pronoun is היא

Even though מזומן is masculine, it is not the grammatical head of the phrase.

Because this sentence means X is not Y, and for that kind of negation Hebrew normally uses לא or a form like אינו / אינה.

So:

• היא לא הוראת קבע = it is not a standing order
• אינה הוראת קבע = it is not a standing order

אין is usually used for non-existence, absence, or there is/are not:

• אין כסף = there is no money
• אין לי זמן = I do not have time

So אין would not be the normal choice here.

Yes. That would be correct, and it sounds more formal or written.

Compare:

• משיכת המזומן היא לא הוראת קבע = normal, common, especially in speech
• משיכת המזומן אינה הוראת קבע = more formal, more concise

Both mean the same thing.

Because here the predicate is being used as a category: the sentence is saying that the cash withdrawal is not a standing order, not that it is not the standing order.

So the predicate is indefinite:

• הוראת קבע = a standing order

If you wanted a definite phrase, you would make the whole construct definite through the second noun:

• הוראת הקבע = the standing order

So the sentence as written is classifying something, not identifying a specific known standing order.

The structure is:

• משיכת המזומן = subject
• היא = linking pronoun
• לא = negation
• הוראת קבע = predicate

So the pattern is basically:

[subject] + [linking pronoun] + [not] + [predicate]

That is a very common pattern in modern Hebrew when negating present-tense nominal sentences.

A simple pronunciation guide is:

meshikhat ha-mezuman hi lo hora'at keva

A few helpful notes:

• משיכת = me-shi-khat
• המזומן = ha-me-zu-man
• היא = hi
• לא = lo
• הוראת = ho-ra-at
• קבע = ke-va

Also, the letter ח in משיכת is pronounced like a throaty kh sound, not like English h.
