Pretty sure there are some
#linguists on Mastodon.
Possibly weird question: the voiceless alveolar sibilant affricate sound in North American English: I notice sometimes that it has found some adoption for initial word sounds where there's no spelling indication that sibilance is part of the word, and indeed where my own pronunciation would not include sibilance.
Is there an accessible paper or anything discussing this phenomenon that might explain theories of its origins in a way a layperson might casually absorb?
I'm really just interested, and cannot even figure out appropriate search strings which might be responsive to this request.
