Indonesian has plural. The plural form is reduplication.
"Apples" is "apel-apel", "Oranges" is "jeruk-jeruk", "Dogs" is "anjing-anjing".
Wait, I remember someone told me they do the plural by repeating the same word? So it woould be "Apel apel, jeruk jeruk". Can someone confirm it or correct me?
Indeed. Why is the answer "apples, oranges" but there is no duplication here?
Two points that I think apply here, taken from a grammar of Indonesian: 1) A noun is not usually reduplicated unless it is unclear from context whether one or more than one is referred to and then only if this is important to what the speaker wishes to convey, 2) Reduplication does not occur if a whole class of things is referred to.
I had the same question! We are expected to guess that both words are plural, when in fact they are (to all appearances) singular!
