Tafadhali jaza fomu hii kabla ya kuingia ofisini.

A simple pronunciation guide is ta-fa-dha-li.

The trickiest part for many English speakers is dh. It is usually pronounced like the th in this, not like the th in thin. So tafadhali sounds roughly like ta-fa-tha-li, with the voiced th sound.

Jaza is the imperative form, used for a direct command or request: fill.

Kujaza is the infinitive, meaning to fill.

So after tafadhali, Swahili uses the command form:

• Tafadhali jaza... = Please fill...

Not:

• Tafadhali kujaza...

Jaza is the singular imperative, so it is directed to one person.

If you were speaking to more than one person, you would usually say:

• Tafadhali jazeni fomu hii...

So:

• jaza = fill out! (to one person)
• jazeni = fill out! (to more than one person)

In Swahili, demonstratives like this usually come after the noun, not before it.

So:

• fomu hii = this form

This is normal Swahili word order. English says this form, but Swahili says form this.

Hii agrees with the noun class of fomu.

Fomu is a loanword and behaves like a noun in the N/N class (often called class 9/10). Nouns in this class often use demonstratives like:

• hii = this
• hizo = those

So:

• fomu hii = this form
• fomu hizi = these forms

Kabla ya means before.

It is a very common expression in Swahili. You can think of it as a fixed phrase:

• kabla ya kuingia = before entering

The word ya links kabla to what follows. So learners should usually remember kabla ya as a set expression.

After kabla ya, Swahili commonly uses the infinitive form of the verb.

So:

• kuingia = to enter / entering

That is why the sentence says:

• kabla ya kuingia = before entering

This is a very useful pattern:

• kabla ya kwenda = before going
• kabla ya kula = before eating
• kabla ya kuanza = before starting

Ofisini means in the office, at the office, or sometimes into the office, depending on context.

It comes from:

• ofisi = office
• ofisini = in/at the office

The ending -ni is a locative ending. It often gives the idea of location:

• nyumbani = at home
• shuleni = at school
• ofisini = at the office / in the office

No, fomu is a loanword, ultimately from English form. Swahili has many loanwords, especially for modern institutions, administration, technology, and education.

Even though it is borrowed, it still fits into Swahili grammar, so you can use it naturally in sentences like:

• fomu hii
• fomu mbili
• fomu hizo

Yes. One common alternative is:

• Tafadhali jaza fomu hii kabla hujaingia ofisini.

This also means Please fill out this form before you enter the office.

The original version with kabla ya kuingia is very natural, especially in written instructions and notices. The version with kabla hujaingia can sound a bit more direct and conversational. Both are correct.
