What is reduplication in Indonesian? (kata ulang)

Short answer

Indonesian reduplication (kata ulang) is doubling a word — like orang-orang (people, plural), berjalan-jalan (to stroll), or kuda-kuda (sawhorse — different meaning than "kuda" = horse). It has three main types: full reduplication (orang → orang-orang), partial reduplication (lelaki from laki, "men"), and modified reduplication (sayur-mayur, where the second word changes). Reduplication forms plurals, intensifies, expresses variety, or creates new meanings.
