nge-

1. used to mark active subject on a verb

   Synonyms: N-, meN- (archaic)

Used before initial consonants b, d, g, h, j, l, m, n, w, y, and one-syllable words. In free variation with assimilating N- before voiced obstruents b, d, j, and g. As with N-, its usage is optional, and bare verbs can also be used transitively. Urban Jakarta dialect in particular seems to have bare forms as the default active transitive verbs, with limited usage of the nasal prefixes.^[1]

• ng- (mainly before vowels or k)
• ny- (mainly before s and c)
• m- (mainly before p)
• n- (mainly before t)

From Javanese N-, either directly or via Betawi N-. The nonassimilating variant is from Betawi nge-, from Sundanese N-, specifically the nga- and nge- allomorphs.
