What I mean is the sound /j/ (as in English yellow and French hyène 'hyena') is the most common semivowel around the world. This phoneme is highly conserved in Indo-European languages (this language family include Italic languages like French and Italian, Germanic languages like English and Dutch, Slavic languages like Russian and Polish, etc.).
Also, the sound /i/ (as in English hippie) (the word hippie is also used in French) in one of the most, if not the most common vowel around the world.
Both phonemes are almost universal, as is the consonant /m/ (as in English mother, and French mère 'mother').
I know many languages that lack the semivowel /w/ like Albanian, Armenian, Greek, and Russian (the semivowel /w/ is found in both English as in world, and French as in oiseau 'bird').
In the universe I am creating, there is a species named ogres (their scientific name is Homo corpulentus 'obese human', so they are still humans, just not Homo sapiens). In the most spoken language used by ogres, there are five basic vowels:
/a/ (as in French arbre 'tree'), the sound corresponding to the /a/ in English gasp;
/ɔ/ (as in English oar, and French ordinateur 'computer');
/u/ (as in English cool, and French ouvrier 'worker');
/y/ (as in French univers 'universe');
and the sound corresponding to French /ø/ (as in euphémisme 'euphemism').
There are no diphthongs in the most spoken language used by ogres, but there are long vowels, and two nasal vowels: /ɑ̃/ as in French antagoniste 'antagonist', and /ɔ̃/ as in French mouton 'sheep; mutton'.
Also, the most spoken language used by ogres has both the semivowel /w/, and the semivowel corresponding to the /ɥ/ in French fruit 'fruit'.
So, I wonder why would a language created by mammals from the Homo genus lack the semivowel /j/, and even the vowel /i/.
