Thanks, Ray! I *believe* something similar happened in some northern
dialects of Norwegian (Tro/mso, I think), where a (palatalized?)
lateral fricative occurs at least intervocally, historically derived
from either *-sl- or *-tl-. Can any of our Scandinavian members comment
on this?

I'm not sure what speech pathologists call it, but I believe that
lateral lisping is not uncommon - did she only do it with /sl-/ clusters
and not on all occurences of /s/? If only with /sl/ then I guess her
idiolect has acquired an interesting shift - one wonders if it is
peculiar to her or occurs with other members of her family or locality?

The extIPA for 'disordered' speech also includes symbols for combinations
of central + lateral fricatives - something like the simultaneous
pronunciation of /K/ and /S/ I gather.
