o have fun with this:
https://en.wikipedia.org/wiki/Dental,_alveolar_and_postalveolar_lateral_approximants
IPA phonology is just a social construct to keep other wise unemployed linguists in employment and off the street
the dark el - is also represented by the polish l - the one with a line thro is and is pronounced like a wubble-u in polish
Basically there are two ( ellz ) in English - they used to be alveolar and velar.
The el within an english word is velar and the tongue goes nowhere near the teeth. The soft palate is just given a twiddle. May be different in the 'pule - they also used the ch in loch as the /k/ sound. terrible. dont go there. Nowadays you have an el and a dark el. One of those subjects where things change but they may not progress.
The irish only have one ( velar I think ) which is why spoken english south of the border sounds 'odd'. One reason anyway.
I dont think your el is an ordinary one with a diacritical mark.
The c-cedilla in romanian isnt an accented letter - it is a letter of itself ( tsa ) and this may be the same
Have fun - I have never found the IPA that helpful - the ghayn of arabic is meant to be the same as the /r/ in Paree. Blimey, is it ? I regard them as two different consonants in the dialects I speak.
anyway if I am wrong - the heavens wont fall in.
