Grammar Rule in 30 Seconds

Nominalization turns verbs or adjectives into nouns using prefixes and suffixes like 'pe-an' or 'ke-an' to describe processes or states.

  • Use 'pe-an' to turn a verb into the process of doing it: 'makan' (to eat) -> 'pemakanan' (the act of eating).
  • Use 'ke-an' to turn an adjective into a state or quality: 'sehat' (healthy) -> 'kesehatan' (health).
  • Use 'pe-an' for the result or place of an action: 'bangun' (to build) -> 'pembangunan' (development/construction).
Root Word + (pe-an / ke-an) = Noun
