Merir, Pulo Anna, Sonsorolese. Significant linguistic differences between Tobian [tox] and Sonsorolese; similar to or greater than differences between, e.g., Puluwatese [puw] and Namonuito [nmt]. 50% intelligibility of Woleaian [woe], less with the remainder of the Trukic continuum. The Merir dialect has been reported to be extinct. Lexical similarity: 69% with Ulithian [uli].
Young Sonsorolese are reported to speak their native language with many English [eng] admixtures. Consequently, their speech is very different from the Sonsorolese of the elder generation, in which there are currently less than 20 speakers over 60 years old. Most also use English [eng] or Palauan [pau].
