I am developing a conlang. For now let's call it "Alanir". I need your help, please. Let's start with a rundown of what I have so far.

Phonology:

Sounds in Alanir are organized into pairs, in which one sound is "Strong" and the other one is "weak". Strong sound is used at the start of a word, and a weak sound is used elsewhere. The glide sound "[j]" does not have a pair and is used only to link vowel sounds.

Consonants (strong :  weak : alphabet letter) :
1. /m(soft)/ - [mʲ] as in million : /m/ - [m] as in “mother” : m;
2. /ng/ - [ŋ] as in “sing” : /n/ - [n] as in “nobody” : n;
3.  /f/ - [ɸ] as in “far” : /v/ - [β] as in “vowel” : v;
4.  /k/ - [k] as in “kettle” : /kh/ - [kʰ] as in “thickhead” : k;
5.  /dj/ - [dʑ] as in “adjacent”; /t/ - [t] as in “temple” : j;
6.  /sh/ - [ʃ] as in “shoes” : /s/ - [s] as in “snake” : s ;
7.  /r(soft)/ - [r̝ʲ] as in “padre” : /g/ - [ɣ] as in “garbage” : r;
8.  /l(soft)/ - [lʲ] as in “linear” : /l/ - [l] as in “lament” : l.

Vowels (strong :  weak : alphabet letter):
1. /wa/ - [wa] or [ɣa] as in “coward” : /ah/ - [ʔa] as in “ahriman” : a;
2. /wo/ - [wo] or [ɣo] as in “war” : /oh/ - [ʔo] as in “dough” : o;
3. /wi/ - [wi:] or [ɣi:] as in “wind” : /i/ - [ʔi] as in “stop it” : i;
4. /wu/ - [wu] or [ɣu] as in “wuhan” : /u/ - [ʔu] as in baffled exclamation sound : u;

Glide: /'/ - [j] - glide as in “toyota” : '.

Tone: No tone phonemes present in this language.

Diacritics (auxillary symbols):
Weak stress  - "-" before the stressed vowel letter, exapmles: kar-il, ra'-ak;
Strong stress -  "_" before the stressed vowel, examples: _akr-il.

Morphology:

All basic words have a structure of CV, VC, VV and are derived from the concept of "akara".
An akara describes a concept as something whole which can be broken down into two concepts which are understood as the opposites of each other by the speakers of the language. An akara is a word having structure of one of the following templates called "kinds".

Each Kind uses fixed set of vowels (akara kind : vowels):

First kind - C1VC1 (Consonant, vowel, same consonant) :  a, u;
Second kind - V1CV1 (Vowel, consonant, same vowel) : o, i;
Third kind - V1V2V1 (One vowel, second vowel, first vowel again): a,o,u,i.

Strategies:

C1VC1: Consonant, vowel, same consonant

Examples:
1. lal : Brightness contrast. (bright, light - la) + (dark, shadow - al)
2. nun : Temporal span. (beginning, start - nu) + (end, finish - un)
3. kak : Causation principle. (cause, reason) - ka + (effect, result - ak)
4. mum : Vertical direction.  (up, above - mu) + (down, below - um)
5. sas : Spatial limit. (in, inside - sa) + (out, outside - as).

V1CV1: Vowel, consonant, same vowel

Examples:
1. oko : Accessibility state. (open - ok) + (closed - ko)
2. iji : Thermal range. (hot - ij) + (cold - ji)
3. ivi : Velocity factor. (fast - iv) + (slow - vi)
4. oro : Affection polarity. (love - or) + (hate - ro)
5. ili : Moral quality. (good - il) + (bad - li).

V1V2V1: One vowel, second vowel, first vowel again
1. a'o'a : Diurnal cycle. (day - a'o) + (night - o'a)
2.  a'u'a : Vital opposition. (life - a'u) + (death - u'a)
3. a'i'a : Causal sequence. (beginning - a'i) + (end - i'a)

You can create new words following one of the strategies below:

First strategy : C1V + C2V -> C1C2V.
Examples: la + ka -> lka, nu + ru -> rnu, so + vo -> svo, mi + ni -> mni;

Second strategy: C1V + VC2 -> C1VC2.
Examples: la + ak -> lak, ro + on -> ron, su + uj -> suj, ki + iv -> kiv;

Third strategy: VC1 + C2V -> VC1C2V.
Examples: al + na -> alna, uj + vu -> ujvu, ok + ro -> okro, ij + si -> ijsi;

Fourth strategy: CV1 + CV2 -> CV1V2.
Examples: ka + ki -> ka'i, su + so -> su'o, ri + ra -> ri'a, jo + ja -> jo'a;

Fifth strategy: VC1 + VC2 ->  VC1C2.
Examples: ar + al -> arl, uj + us -> ujs, or + ok -> ork, in + im -> inm.
