I just heard on the following SNL skits, entitled "Mid-Day News" from the October 5, 2019 episode hosted by Phoebe Waller-Bridge:
climbing clearly pronounced as /klaimbɪŋ/ instead of the expected /klaimɪŋ/ by two different speakers playing the part of journalists.
This is a first for me.
Do some people also pronounce climb as /klaimb/? How widespread and recent is this spelling pronunciation? Is this specific to American English? Since the whole skit is about rivalry between Whites and Blacks, could it be a marker of Black American English?
