Pegawai mengawasi pintu masuk.

Pegawai is a noun meaning officer, official, staff member, or employee, depending on context.

In this sentence, pegawai is most naturally understood as the officer or an officer. If the setting is government or security, officer is a good translation. In a business setting, it could also mean staff member or employee.

The base form is awas, which is related to being alert or watchful.
To make it into the active verb to supervise / to monitor / to watch over, Malay uses:

• the prefix meng-
• the suffix -i

So:

• awas → alert / careful
• mengawasi → to watch over, monitor, supervise

The meng- prefix is a very common active verb marker in Malay.
The -i suffix often gives the sense of doing something to, at, or over an object or location.

So mengawasi pintu masuk means to monitor/watch over the entrance.

Not exactly.

• melihat = to see / to look at
• menonton = to watch something like a movie, show, or match
• mengawasi = to supervise, monitor, keep an eye on, watch over

So if someone is guarding or monitoring an entrance, mengawasi is the right choice.

Literally, it is:

• pintu = door
• masuk = enter / go in

Together, pintu masuk means entrance or entry door.

This kind of noun combination is very common in Malay. Another useful one is:

• pintu keluar = exit

So even though the words are literally door + enter, the natural English meaning is entrance.

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

So Pegawai mengawasi pintu masuk could mean:

• The officer is monitoring the entrance
• An officer monitors the entrance
• The officer monitors an entrance

The exact meaning depends on context.

If Malay wants to be more specific, it often uses context, word order, or words like ini (this) and itu (that), rather than a direct equivalent of English articles.

Yes. The sentence follows the very common Malay pattern:

Subject + Verb + Object

• Pegawai = subject
• mengawasi = verb
• pintu masuk = object

So the structure is very similar to English:

• The officer
  • monitors
    • the entrance

This makes basic Malay sentences feel quite familiar to English speakers.

Not by itself. Malay verbs do not change form for tense the way English verbs do.

So mengawasi can mean different things depending on context, such as:

• monitors
• is monitoring
• monitored
• sometimes even will monitor, if the context makes that clear

If you want to make the time clearer, Malay often adds time or aspect words such as:

• sedang = in the middle of / currently
  
  • Pegawai sedang mengawasi pintu masuk.
  • The officer is monitoring the entrance.
• sudah / telah = already / has
  
  • Pegawai telah mengawasi pintu masuk.
• akan = will
  
  • Pegawai akan mengawasi pintu masuk.

By itself, pegawai does not clearly mark singular or plural. Context usually tells you.

So pegawai can mean:

• an officer
• the officer
• sometimes even officers, if the situation makes that clear

If Malay wants to mark plural more clearly, it can use:

• pegawai-pegawai = officers
• para pegawai = officers / the officers

In this sentence, most learners would read it as singular unless the wider context suggests otherwise.

A rough English-friendly guide is:

• Pegawai → puh-GAH-wye
• mengawasi → muh-ngah-WAH-see
• pintu masuk → PEEN-too MAH-sook

A few helpful notes:

• ng in meng- sounds like the ng in sing
• u in Malay is usually like oo in food
• Malay stress is usually lighter and less dramatic than English stress

So it is best not to over-stress the words too much.

A natural passive version is:

Pintu masuk diawasi oleh pegawai.

This means The entrance is monitored by the officer.

Here:

• diawasi = passive form of mengawasi
• oleh = by

So the contrast is:

• Pegawai mengawasi pintu masuk. = active
• Pintu masuk diawasi oleh pegawai. = passive

Malay uses passive constructions quite often, so this is a useful pattern to learn early.
