Cthuvian

Introduction
Cthuvian, which is also called R'lyehian, is a fictional langauge created by H.P. Lovecraft. It is spoken in a fictional universe called Cthulhu Mythos. This language has an unfamiliar phonology compared to Human Language. It appeared in The Call of Cthulhu, a short story written by Lovecraft.

Feeling excited, right? Let's get started.

Phonology
Since R'lyehian is an alien language, it has a weird syllable structure , CCCCVCC. Terrible, right? The 'h' can be used in two ways:
 * When it follows a consonant, it softens its pronunciation. So, "ph" sounds like "f".
 * It also stands on its own and sound as "ha", "hu" etc.

Grammar
R'lyehian nouns, verbs and other [https://compopedia.fandom.com/wiki/Parts_of_speech#:~:text=Parts%20of%20speech,%2C%20prepositions%2C%20conjunctions%20and%20interjections. parts of speech] are indistinguished from one another. This language is a fusional language, means prefix+noun+suffix construction are common. Prepositions are also prefixed, "ph-" is a prefix for "beyond". "ph'shugg" means "beyond the earth". There are other prefixes such as "ng-" (and then), "mg-" (still), etc. The last repeated syllable changes the noun from singular to plural. So, "n'gha" means "death" and "n'gha-ghaa" means "deaths". The past tense is made by adding the prefix "nafl-" to the verb. So, "sll'ha" means "you are giving (offer)." and "nafl'sll'ha" means "you gave (offer)". Although the word order  is free, sometimes the object get prefixed to the verb, which is awkward.

Analysis
A famous sentence in "The Call of Cthulhu " in Cthuvian language is given below:

"ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn": ("In his house at R'lyeh dead Cthulhu lies dreaming.")

Literally translated as:

"Over the limit (dead), still dreaming, Cthulhu, (at) R'lyeh, (in) the residential place (palace), lies."

The Cthulhu Mythos is different from our world so word-to-word translation from English to R'lyehian is not possible.
