Japanese[edit]

Etymology[edit]

Generally agreed upon as originating from baby talk.[1][2][3][4]

Derivation unclear. Possibilities include:

/wo wo umai//o o umai//oːmai//opːai/
While suggestive, the phonetic changes required seem unlikely. Moreover, the pitch accent differs, in that うまい (umai) has a high pitch on the ma followed by a downstep, while おっぱい (oppai) has a high pitch on the initial o followed by a downstep.
  • A shift from 一杯 (ippai, one serving, one cupful; full),[4] as something a baby might say when done breastfeeding, or when asking to do so.
/ipːai//opːai/
This seems more likely, as the phonetics align better: only one vowel changes, and the pitch accent in ippai is similar with a high pitch on the initial i followed by a downstep.
