Let’s Make a Conlang: Soleisu Week 1

<< Let’s Make a Conlang: Introduction | Let’s Make a Conlang: Soleisu Week 2 >>

I’ve technically been working on this conlang since December 1st – after all, I am using it for Lexember – but surprisingly, I’ve had very little time to work on it. All I’ve created so far are the phonology, orthography, and noun cases. I thought I’d have the opposite problem – that I’d speed through the conlanging process and be “done” in just a few weeks. Looks like this will be a longer series of blog posts after all.

I decided yesterday that this conlang would be called soleisu. What does soleisu mean? Uh…at the moment, I have no idea. I made the word, but I haven’t assigned a meaning to it yet. And it definitely can’t mean “language”, since the word for that is kala.


Soleisu has a rather small (for me) consonant inventory. Three stops with no voicing distinction, two fricatives, and two approximants. It doesn’t have /r/ or /w/, which most of my languages include.

m n


p t k

Fricative s


Approximant l j

It took me a while to figure out what kind of consonants I wanted. I eventually decided on a smaller consonant inventory because it would make the initial consonant mutations (something I had in mind from the very beginning) much more regular. Those consonant mutations will be explained in the noun case section.


The vowels here are nothing special. I deliberated for a while with whether or not I wanted /y/, but then threw it in anyway because…I don’t actually remember the reason. It’s just there now.

Open a

Soleisu also has a few diphthongs: /ai/, /ei/, /ou/, and /oi/. If I remember correctly, I added these because I wanted the language to look more like Ancient Greek. I don’t think I succeeded in that regard.

Syllable Structure

Syllable structure is CV, with two finals – /n/ and /l/. They can only exist mid-word, never at the end of a word.

I considered having more final consonants, but then decided against it for a reason I don’t remember. This may change in the future. I think I want /s/ as a final as well.


I deliberated for a while how I wanted to represent /y/ and /j/. /j/ was originally represented with <j> and /y/ with <y>, but I thought that might make the language look a little too much like Finnish.

Noun Cases

I knew from the beginning that I wanted to use initial consonant mutations, but not in what way. I eventually decided on using consonant mutations to indicate case. This meant that there could only be a few cases, so I decided on three: nominative, genitive, and dative.

It didn’t take me very long to figure out how to create the genitive case through consonant mutations: every consonant became a fricative. The dative case took a lot more thought. I eventually decided on making each initial consonant “harder” – they shifted to stops.

In the genitive case:

  • Initial consonants become fricatives
  • /h/ is deleted
  • /s/ becomes [ʃ]
  • Initial vowels are prefixed with /h/.

In the dative case:

  • Nasals are prefixed with /t/
  • Stops are unchanged
  • /s/ becomes [ts] and /h/ becomes [t]
  • /j/ becomes [dʒ]
  • /l/ becomes [tl]
  • Initial vowels are prefixed with /t/


Genitive Dative




[ʒ] [dʒ]




[ɬ] [tl]


[v] [tm]


[h] [tn]


/s/ [ʃ]


/t/ [θ]

/a/ [ha]


/e/ [he]


/i/ [hi]


/o/ [ho]


/u/ [hu]


/y/ [hy]


Here are some examples:
