-lle

Etymology
From or, related to and probably a variant of  or  (whence dialectal , ), which is related to  and is composed of -l(l)- (external locative suffix) +  (with an epenthetic *-e-). Compare Erzya and 🇨🇬.

It is not known whether the short *-l- or long *-ll- is original. If short, the long -l- may be due to analogy with,. The answer likely depends on the origin of the -l- itself. The traditional theory posits that it comes from the toponymic suffix, but more recently it has been proposed that it is in fact a reduction of ; thus >  >  >. The initial genitive ending is lost by reduction of a phonotactically impossible sequence, but not in >, hence.
