Questions & Answers about Jaringan internet lambat malam ini.

What does each word in the sentence mean, and what roles do they play?

• jaringan: network (noun). From root jaring (net) + suffix -an.
• internet: internet (noun, loanword). Here it modifies jaringan (a noun-noun compound).
• lambat: slow (adjective).
• malam ini: tonight/this evening (time phrase: malam = night, ini = this).

Overall pattern: Noun Phrase (jaringan internet) + Adjective (lambat) + Time Adverbial (malam ini).

Why is there no word for “is” in the sentence? Can I add adalah?

Indonesian doesn’t require a linking verb before adjectives. Adjectives can serve as the predicate on their own: X lambat = “X is slow.” The word adalah is generally used to equate two nouns (e.g., Dia adalah dokter). It is not used before adjectives, so Jaringan internet adalah lambat is unnatural.

Is the word order noun–adjective? Could I put lambat before jaringan internet?

Yes, adjectives normally follow the noun they describe. So jaringan… lambat is correct. Placing the adjective first (lambat jaringan internet) is ungrammatical in standard Indonesian.

Can the time phrase malam ini be moved to the front or omitted?
