percayai

From percaya +‎ -i.

• (Standard Indonesian) IPA^(key): /pərt͡ʃaˈjai/ [pər.t͡ʃaˈja.i]
• Rhymes: -ai
• Syllabification: per‧ca‧ya‧i

pêrcayai (active memercayai, passive dipercayai)

1. (transitive) to trust

The active form is sometimes mempercayai (probably influenced by the fact that the first syllable of the word is similar to the causative prefix per-, which is not affected by nasal mutation of meng-), but it's proscribed.
