A prefix is attached before the base or root word. A number of sound changes occur when the following prefixes are combined with root words in order to facilitate a smooth transition in pronunciation. What the sound will be in a particular word depends on the first sound of the root word following the prefix.
Examples
| First Letter | Inflection | Root Word | Example | Meaning |
| l m ny r w | me + root | lihat masak nyanyi rusak wabah | melihat memasak menyanyi merusak mewabah | to see to cook to sing to destroy to become epidemic |
| Vowel g h | me + ng | alir gali hapus | mengalir menggali menghapus | to flow to dig to erase |
| c d j | me + n | cuci didik jual | mencuci mendidik menjual | to wash to educate to sell |
| b f v | me + m | buat fokus vonis | membuat memfokus memvonis | to make to focus to sentence |
| First Letter | Inflection | Root Word | Example | Meaning |
| k | me + ng + drop the ‘k’ | kenang | mengenang | to remember |
| t | me + n + drop the ‘t’ | tulis | menulis | to write |
| s | me + ny + drop the ‘s’ | sapu | menyapu | to sweep |
| First Letter | Inflection | Root Word | Example | Meaning |
| p | me + m + drop the ‘p’ | pilih | memilih | to choose |
| p* | me + m + root word + suffix ‘i’ | punya pengaruh | mempunyai mempengaruhi | to have, to own to influence |
*) In this case first letter or initial ‘p’ is retained.
With single syllable bases, which are all borrowings from other languages, me- optionally becomes menge-. In this case initial p. t. s and k are not lost as forms without them would sometimes be difficult to interpret.
Examples
