Skrreean language
Skrreean language was the language spoken by the Skrreea. The language had a unique syntax and grammatical structure, unlike any other language in Starfleet's database prior to first contact with the species in 2370.

Spoken language
Deep Space 9's universal translator initially had difficulty analyzing its language patterns, and the first Skrreean visitors to the station were made to keep talking so that the computer could establish a translation matrix. 

Skrreean didn't have a word for husband, a Skrreean woman would instead describe her men as "bonded to her." ()

Words and phrases
Creshnee – Other (as in 'other side of a wormhole.')
Intaowa – An expression that something is hideous.
Jeetaka – million
