In many Romance languages, nicknames come from baby talk- or, more accurately, from babies’ first attempts to say their own names.
A Mexican toddler named Guilermo (William) will often pronounce his name “Memo.” So, not surprisingly, “Memo” is the Mexican equivalent of “Billy.”
The Italian version of Joseph/Jose is “Giuseppe.” An Italian toddler with that name often pronounces it “Pepe,” which has become one of several popular Italian equivalents of “Joey.”
I was going to say Ted for Edward and Sally for Sarah. I’ve never understood either of them.
If someone’s name was Ted, I’d assume it was short for Theodore. That makes more sense to me.
The Sally for Sarah is just like Jack for John. Same number of letters and syllables. Both of them get a big ole’ WTF? from me.
In the South, for a long time, William Horace Jones II would be known as “Dub,” while William Horace Jones III would be known as either “Trip” or “Trey.”
After a while, though, I think “Trey” took on a life of its own, and a fair number of kids now have “Trey” on their birth certificates.
I’m assuming this is pure coincidence, but maybe there’s a reason behind all of this.
One of my oldest friends (we’ve known each other since Kindergarten 56 years ago) is named Harold, known all his life to parents, friends, classmates, coworkers, girlfriends, and wife as “Hal.”
But… his sister (two years younger) always called him “Butchie”, and his brother (four years younger) always called him “Butch.” When we were kids I sometimes asked them why, and they always shrugged and said they didn’t know. We were all in our fifties before I noticed them addressing him as Hal."
