Tetun has no special words for "a", "an", or "the" but "IDA" meaning "one" can perform these functions, e.g. FAHI IDA a/the pig. The plural article is formed by adding "SIRA", e.g. FAHI SIRA, the pigs.
Adjectives always follow the noun without exception. They may be formed from other words that end in a vowel by adding the letter K. Nouns and other words ending in N may change this to Km but are often left as they are. Some adjectives are formed by prefixing "HAK" but mostly "NAK", particularly those with a verbal sense.
