Other comments: Gumawana or Gumasi has a quinary counting system with one word for ten and and a phrase for twenty 'koroto tayamo ikamasa' which means 'one man is dead'. However, people use English borrowings or Pisin now often. The language is still strong but with kids going to school now, they are saying a lot of English. For 'twenty' I rarely hear 'koroto tayamo ikamasa'. Typically they will say tuwenti. They tend to use only English for numbers greater than twenty. Gumawana is an endangered language spoken by about 400 speakers in Amphlett Islands, Milne Bay province, Papua New Guinea.
