In the classic tradition of thinking that “dang” is pronounced “dang” and not “Dan G.” I propose that we read “tomhow” as “Tomh Ow”.
I prefer the dyslexic pronunciation of towhom.
I have people call me Joenot - in reality, this username was chosen decades ago by my mother, pairing Joe (my name) and Not(tawa) - my tiny hometown.
Sometimes I wish I'd chosen better but like many names, once it's out there, it tends to stick.
WAIT WHAT?!?
Pronounced exactly as "to meow"
