Dia melabel kotak dan menggunakan pita pelekat.

Yes. Dia can mean he or she.

Malay third-person singular pronouns usually do not mark gender, so dia melabel kotak could mean:

• He labels the box
• She labels the box
• He is labeling the box
• She is labeling the box

The exact meaning depends on context.

Malay usually does not use articles like English a, an, or the.

So kotak can mean:

• a box
• the box
• boxes, in some contexts

The listener figures it out from the situation or from extra words in the sentence.

For example:

• Dia melabel kotak = He/She labels a box / the box
• Dia melabel kotak itu = He/She labels that box / the box
• Dia melabel sebuah kotak = He/She labels a box

Melabel means to label.

It is built from the borrowed word label plus the active verb prefix meN-. In this case, it becomes melabel.

This meN- prefix is very common in Malay and often creates an active verb meaning to do something:

• baca → membaca = to read
• guna → mengguna / menggunakan = to use
• label → melabel = to label

So melabel is the active verb to label.

Yes, indirectly. Label is a loanword in Malay, and Malay can attach its own verb-forming prefixes to borrowed words.

That is very normal in Malay. A borrowed root can behave like a Malay root once it enters the language.

So melabel is a natural Malay verb, even though the base word comes from English.

Both are related to use, but menggunakan is the fuller, more formal verb form.

• guna can be a noun or a simpler verb in everyday speech
• menggunakan is a standard transitive verb meaning to use

So:

• Dia menggunakan pita pelekat = very standard, clear
• Dia guna pita pelekat = common in casual speech

Both are understandable, but menggunakan sounds more formal or textbook-like.

A learner may see all three, but they are not equally common.

• guna = use; often used informally in speech
• mengguna = possible, but less common in everyday standard usage
• menggunakan = the most standard form for to use something

In a sentence with a direct object, menggunakan is very natural:

• Dia menggunakan pita pelekat. = He/She uses adhesive tape.

So if you are unsure, menggunakan is the safest standard choice.

Literally, it means something like adhesive tape.

• pita = tape / ribbon / strip
• pelekat = adhesive / sticking

Together, pita pelekat means adhesive tape, such as packing tape or sticky tape, depending on context.

It is a descriptive compound noun.

No. There are other ways, depending on region and context.

Some possibilities are:

• pita pelekat = standard adhesive tape
• selotip = common borrowed word for sticky tape in some contexts
• pita pembungkus = packing tape, if you want to be more specific

So pita pelekat is correct and standard, but in real life you may hear other terms too.

Malay usually follows Verb + Object order in sentences like this.

So:

• melabel kotak = label the box
• menggunakan pita pelekat = use adhesive tape

This is similar to English:

• label the box
• use tape

If you say kotak melabel, that would not normally express label the box.

By itself, kotak does not clearly show singular or plural.

So Dia melabel kotak could mean:

• He/She labels the box
• He/She labels boxes

Context decides the meaning.

If Malay wants to make plurality clearer, it can use reduplication:

• kotak-kotak = boxes

But Malay often leaves nouns unmarked for number unless it really matters.

Because one subject can apply to both actions.

In Dia melabel kotak dan menggunakan pita pelekat, the subject dia belongs to both:

• Dia melabel kotak
• (Dia) menggunakan pita pelekat

Malay, like English, does not need to repeat the subject if it is the same person doing both actions.

So the sentence means that the same person both labels the box and uses adhesive tape.

Dan means and.

It joins the two verb phrases:

• melabel kotak
• menggunakan pita pelekat

So the sentence describes two actions done by the same person:

1. labeling the box
2. using adhesive tape

It could be either. Malay verbs usually do not change form for tense the way English verbs do.

So Dia melabel kotak dan menggunakan pita pelekat could mean:

• He/She labels boxes and uses adhesive tape
• He/She is labeling the box and using adhesive tape

Time is usually understood from context, or shown with time words such as:

• sekarang = now
• semalam = yesterday
• setiap hari = every day

For example:

• Sekarang dia melabel kotak dan menggunakan pita pelekat. = Right now he/she is labeling the box and using adhesive tape.
• Setiap hari dia melabel kotak dan menggunakan pita pelekat. = Every day he/she labels boxes and uses adhesive tape.

A simple English-friendly guide:

• dia ≈ DEE-ah
• melabel ≈ muh-LA-bell
• kotak ≈ KOH-tak
• dan ≈ dahn
• menggunakan ≈ muhng-GOO-nuh-kan
• pita pelekat ≈ PEE-tah puh-LEK-at

A few helpful notes:

• Malay pronunciation is usually more regular than English.
• Most letters are pronounced.
• The e in some Malay words can sound like a schwa, like the a in about.

Yes, it is grammatical and understandable.

It sounds fairly neutral to slightly formal because of words like menggunakan. In casual speech, a speaker might say something a bit simpler, such as:

• Dia label kotak dan guna pita pelekat.

That is more conversational.
The original sentence, though, is perfectly good standard Malay.

Yes, depending on what exactly you mean by label.

If you mean attach a label, Malay might also use expressions like:

• meletakkan label pada kotak = put a label on the box
• menampal label pada kotak = stick a label onto the box

But if you simply want the verb to label, then melabel is a good direct choice.

So:

• melabel kotak = label the box
• menampal label pada kotak = more literally stick a label onto the box

Both can work, but they focus slightly differently on the action.
