Classical Adûnaic had no restrictions on what consonants could appear finally, except for [ŋ] which could only appear medially before [g] (SD/433 note #5). Final consonant clusters were not allowed, however (SD/418, 426). The only exception was that, towards the end of Classical Adûnaic, a short final [a] was lost at the end of a phrase, but this was not reflected in writing (SD/418). Presumably the [a] was restored if any suffixes were added.
