Yelmek language
Yelmek, also rendered Jelmek or Jelmik, is a language of the proposed Trans-Fly – Bulaka River family in West Papua. Yelmek is spoken west of Merauke, between the Digul River and Mbian River. Notable villages are (from north to south) Yelwayab on the Wanam River, Bibikem, Woboyo, and Dodalim (Dudaling). Related Maklew is spoken in Welbuti village. The Wanam variety might be a distinct language. Phonology 

The fricative phonemes are both marginal. /s/ appears in only a small number of words, most of which are known to be loans. Speakers are not consistent either between each other or themselves in which words contain /h/, with many words claimed to have it being pronounced without it, and words that lack it surfacing with it, in an apparent case of hypercorrection. Grammar 

Nouns in Yelmek are not morphologically complex. They have gender and number, but these are not marked on the noun itself, but on other parts of the sentence; number and gender are marked on the verb, and number is also marked on attributive modifiers of the noun. Modifiers in Yelmek occur in their underived root form when functioning as the predicate of a clause, but to serve as an attributive modifier within a noun phrase, must take an attributive suffix, which agrees in number with the head noun. Case marking occurs at the level of the noun phrase, not the noun, with the final element of the noun phrase being followed by a case assigning clitic or postposition. References
