What is a strange or incomprehensible language?

Answer 1

A strange or incomprehensible language is called a lingo. It can be a foreign language, the special vocabulary of a field of interest such as a lawyer or doctor, or language characteristic of an individual.

Answer 2

Language that is considered strange or incomprehensible could be one that is extremely rare, like an endangered indigenous language with very few speakers. It could also refer to a constructed language like Klingon, created for a fictional world. Lastly, languages with complex grammar or unique phonetic features, like Taa with its extensive click consonants, can also be seen as strange or incomprehensible.
