Gece lambası hâlâ açık.

Turkish often leaves out the verb to be in the present tense.

So Gece lambası hâlâ açık literally looks like:

• gece lambası = night lamp / bedside lamp / nightlight
• hâlâ = still
• açık = open / on

But the full meaning is The night lamp is still on.

This kind of sentence is called a nominal sentence. In the present tense, Turkish usually does not need an extra word for is / are.

Compare:

• Kapı açık. = The door is open.
• Su soğuk. = The water is cold.
• Gece lambası açık. = The night lamp is on.

If you wanted past tense, then Turkish would show it more explicitly:

• Gece lambası açıktı. = The night lamp was on.

This is because gece lambası is a noun compound in Turkish.

It is built like this:

• gece = night
• lamba = lamp
• lamba-sı = lamp + compound/possessive ending

So gece lambası literally looks like night its-lamp, but in natural English it means night lamp, bedside lamp, or nightlight, depending on context.

This pattern is very common in Turkish:

• okul kapısı = school door
• mutfak masası = kitchen table
• araba kapısı = car door

So even though English often puts two nouns together directly, Turkish usually marks this kind of compound on the second noun.

It is both understandable word by word and also a very natural set phrase.

Word by word, it is:

• gece = night
• lambası = lamp in compound form

Together, gece lambası commonly means a lamp used at night, especially a bedside lamp or nightlight.

So yes, you can analyze it grammatically, but you should also learn it as a normal vocabulary item.

Hâlâ means still.

It shows that a situation continues when you might have expected it to change.

So in this sentence, the idea is:

• the lamp was on before
• it has not been turned off yet
• it is still on

Examples:

• Hâlâ burada. = He/She is still here.
• Hâlâ uyuyor. = He/She is still sleeping.
• Hâlâ açık. = It is still open/on.

The circumflex in hâlâ helps distinguish it from hala.

• hâlâ = still
• hala = paternal aunt

In everyday typing, many people omit the circumflex and just write hala, so context often tells you which meaning is intended. But in careful writing, hâlâ for still is useful and standard.

Yes, açık often means open, but it can also mean on, unclosed, uncovered, or lit, depending on context.

With lights and electrical devices, açık commonly means on:

• Işık açık. = The light is on.
• Televizyon açık. = The television is on.
• Gece lambası açık. = The night lamp is on.

Its opposite is kapalı, which can mean closed or off:

• Kapı kapalı. = The door is closed.
• Işık kapalı. = The light is off.

So Turkish uses the same adjective pair in several related situations.

Turkish does not have articles like English a/an and the.

So Gece lambası hâlâ açık can mean:

• The night lamp is still on
• or, depending on context, A night lamp is still on

Usually the context tells you which one sounds best in English.

This is very normal in Turkish. For example:

• Kapı açık. = The door is open.
• Çocuk uyuyor. = The child is sleeping / A child is sleeping

English requires an article, but Turkish usually does not.

The given order is natural and neutral:

• Gece lambası hâlâ açık.

This puts the topic first, then hâlâ, then the descriptive word açık at the end.

Turkish word order is somewhat flexible, but changing it changes the emphasis.

For example:

• Gece lambası açık. = The night lamp is on.
• Gece lambası hâlâ açık. = The night lamp is still on.
• Hâlâ açık gece lambası is not a normal full sentence in this form; it sounds more like part of a noun phrase.
• Gece lambası açık hâlâ is possible in speech, but it sounds more marked or emphatic.

For learners, the original order is the best one to use.

A simple pronunciation guide is:

• gece ≈ geh-jeh
• lambası ≈ lahm-bah-suh
• hâlâ ≈ haa-laa
• açık ≈ uh-chuk

A few important points:

• c in Turkish is pronounced like English j in jam
• ç is like ch
• ı is the Turkish vowel with no exact English equivalent; it is a relaxed, central/back vowel, not ee

So açık is not achik with a clear i sound. The last vowel is the special Turkish ı.

Yes, and that is a useful comparison.

• Gece lambası açık. = The night lamp is on.
• Gece lambası yanıyor. = The night lamp is burning/shining, meaning it is lit or on.

Both can work for a light. The difference is:

• açık describes its state: it is on
• yanıyor describes the ongoing action/state of burning or shining

With hâlâ, both are possible:

• Gece lambası hâlâ açık.
• Gece lambası hâlâ yanıyor.

The version with açık is very common and natural for switches, lights, and devices.

Yes. Açık is a very common adjective with several related meanings.

Examples:

• Kapı açık. = The door is open.
• Pencere açık. = The window is open.
• Mağaza açık. = The shop is open.
• Televizyon açık. = The TV is on.
• Telefon açık. = The phone is on.

So when learning açık, it is best not to memorize only one English equivalent. Think of it as a broad word meaning something like open / on / active, depending on context.
