Magudanar tana a bayan gidan.

Magudana is the basic noun form. Magudanar is the specific/definite form, often corresponding to the drain or that drain in English.

In Hausa, this idea is often shown by a noun ending rather than by a separate word like the. For a feminine singular noun, that ending is often -r.

Here, tana works roughly like it is in English.

More specifically, it is the form Hausa uses here for a feminine singular subject in a locational sentence. Since magudanar is feminine singular, tana is the matching form.

Because that is normal Hausa sentence structure.

Even when the subject noun is stated openly, Hausa usually still includes a matching subject marker in the clause. So Magudanar tana... is not unusual repetition; it is standard grammar.

Yes, grammatically it is feminine.

This is grammatical gender, not biological gender. In Hausa, many inanimate nouns are treated as masculine or feminine, and that affects agreement words like tana.

A is a location marker.

Depending on context, it can correspond to English at, in, on, or just a general idea of location. In this sentence, it introduces the place phrase bayan gidan.

Bayan can mean back, behind, or in some contexts after.

Here it is being used in a location expression, so bayan gidan means behind the house or more literally at the back of the house.

Gida is the basic form of the noun. Gidan is the specific/definite form, often corresponding to the house.

So bayan gidan means behind the house. Just like magudanar, the noun is carrying the definiteness idea in its ending.

Not the way English has one.

Hausa often shows definiteness or specificity by changing the form of the noun itself, especially with endings like -n and -r. In this sentence, magudanar and gidan are doing that job.

The pattern is:

subject + agreeing marker + location phrase

So here it is:

Magudanar + tana + a bayan gidan

That is the normal way to say this kind of idea in Hausa.

Not with magudanar.

Yana is the matching form for a masculine singular subject, while tana is for a feminine singular subject. Since magudanar is feminine, tana is the correct choice.

Not exactly word-for-word.

A more literal breakdown is at the back of the house:

• a = at/in a place
• bayan = back/behind
• gidan = the house

But natural English usually says behind the house, so that is the best translation.

Yes.

Besides behind or at the back of, bayan can also mean after, depending on the sentence. Hausa often uses the same word for related ideas like physical position and sequence in time.
