@Samaalic Era Listen to Shibbane, he's right.
Xarfo= Shibannayaal+Shaqalle
Shaqal gaaban: a,e,i,o,u.
Shaqal dheer(Double vowels): aa,ee,ii,oo,uu.
Shibbane: b,t,j,x,kh,d,r,s,sh,dh,c,g,f,q,k,l,m,n,w,h,y.
Shibbanaha labanlaabma(Double consonants):
Ma
na
la
ga
raa
d baa? aka m,n,l,g,r,d,b.
Some linguists also tend to add:
Dh: Without a doubt, Dh
can be a double consonant.
For example: (Iyada/Feminine): Hadhay(should actually be Hadhdhay), Xidhay=Xidhdhay, Badhay=Badhdhay, Gabadha=Gabadhdha, Weedha=Weedhdha etc.
Guddiga(the committee) deemed it would be "too ugly" to write double DHs, that's why poor dh is almost never mentioned along with other double consonants despite being one.
According to my awoowo, a lot of linguists were from the very beginning against consonants like DH, SH and KH, they wanted to replace them with other letters we don't use like V, P and Z.
Y= Tends to Flip-flop between being Shibbane and Shaqal.
These articles explain the importance of the double consonants:
