Usifungue kiambatisho kabla ya uthibitishaji wa mtumaji.

Usifungue is a negative command addressed to one person: don’t open.

It breaks down like this:

• usi- = negative marker for you singular in commands
• fungu- = verb stem from -fungua, meaning open
• -e = the final vowel used in this negative/subjunctive form

So the basic positive command is fungua = open!, but the negative command becomes usifungue = don’t open!

In Swahili, the final -a of many verbs changes to -e in the subjunctive-type form, and that form is used in several situations, including negative commands.

So:

• -fungua = to open
• fungua! = open!
• usifungue! = don’t open!

This is a very common pattern, so it is worth learning early.

Usifungue is for one person.

If you are speaking to more than one person, use:

• Msifungue kiambatisho kabla ya uthibitishaji wa mtumaji.

So:

• usi- = don’t you (singular)
• msi- = don’t you (plural)

In public notices, instructions, or formal warnings, plural forms are often used because they can sound more general or more polite.

Kiambatisho means attachment or enclosure, especially in contexts like email or documents.

It is related to the verb -ambatisha, which means to attach.

So the idea is:

• -ambatisha = attach
• kiambatisho = attached thing / attachment

This is a good example of how Swahili often builds nouns from verbs.

Kiambatisho is in the ki-/vi- noun class:

• singular: kiambatisho
• plural: viambatisho

So if you wanted to say attachments, you would use viambatisho.

Examples:

• hiki kiambatisho = this attachment
• hivi viambatisho = these attachments

This noun class is very common, so it is useful to recognize ki- as singular and vi- as plural.

Yes, it could also be plural, depending on context.

The singular kiambatisho can refer to:

• one specific attachment, or
• an attachment in a general sense

The plural viambatisho would be used if you clearly mean attachments.

So both can make sense:

• Usifungue kiambatisho... = Don’t open the attachment / an attachment
• Usifungue viambatisho... = Don’t open attachments

Swahili often relies on context rather than articles like a or the.

Kabla ya means before.

It is a fixed expression that is followed by a noun or noun-like phrase.

In this sentence:

• kabla ya uthibitishaji = before verification

You will also see it with infinitives:

• kabla ya kuondoka = before leaving
• kabla ya kusoma = before reading

So kabla ya is a very useful phrase pattern to memorize as a whole.

Uthibitishaji means verification in the sense of the act or process of verifying.

It comes from -thibitisha, meaning to confirm / verify / authenticate.

A helpful distinction is:

• uthibitishaji = verification, the process of checking
• uthibitisho = proof, confirmation, evidence, or the result of confirming

In a security or email warning, uthibitishaji fits well because the sentence is talking about checking whether the sender is legitimate.

The wa here is the associative/genitive connector, often translated as of.

So:

• uthibitishaji wa mtumaji = verification of the sender

A key point for learners is that this connector agrees with the first noun, not the second one.

Here the head noun is uthibitishaji, and that noun takes wa in this structure. That is why we get:

• wa mtumaji

not because mtumaji is a person, but because uthibitishaji is the noun being linked.

Mtumaji means sender.

It comes from the verb -tuma, meaning to send.

The ending -ji often helps form a noun for the person who does an action. So:

• -tuma = send
• mtumaji = sender

Its plural is:

• watumaji = senders

This word is very common in email, messaging, and document-related contexts.

Swahili normally does not use separate articles like English a/an/the.

So a noun like kiambatisho can mean:

• an attachment
• the attachment
• sometimes just attachment in a general sense

The exact meaning depends on context.

If Swahili wants to be more specific, it often uses other tools, such as:

• context
• demonstratives like hiki = this
• possessive structures
• word order and situation

That is why the sentence sounds complete even without an article.

Yes. The order is very normal:

• Usifungue = verb
• kiambatisho = object
• kabla ya uthibitishaji wa mtumaji = time/prepositional phrase

So the structure is basically:

• Don’t open + attachment + before verification of sender

Swahili commonly places the verb first and then follows it with the object and other information, so this sentence is quite straightforward in structure.
