u
you
ewe
hew
yew
Hugh
hue
Can you add to this list of different meanings for this common vocalization?
Any other vocalizations that can generate a list as long as the above?
Don’t you pronounce the “h” in hew, Hugh, and hue?? I only see three homonyms for “u” in your list (you, ewe, and yew).
The word "u"
“U” is not a word.
Sue me.
Kinda sorta there’s:
the Chinese name “Yoo” (Robert van Gulik used the confusion between “Yoo” and “you” as a plot point in one of his “Judge Dee” mysteries)
Russian letter “yu”
The expression “Eww!”
I have to admit, thoughts of all these run through my head whevnever I hear the song “I’ll stand by You”
I’ll Stand by You
I’ll Staa-aand by Hugh
I’ll stand by Yew
Throughout your darkest Hour
I’ll stand by “U”
I’ll stand by Ewe…
etc.
Depends on the language. In Afrikaans, “u” is a word meaning, (ahem) you. It is used when addressing someone you don’t know or when dealing with someone in a professional environment.
So, where can I deliver the summons?
And pronounced “oo”, except at the back and top of the mouth in a way that no non-South African will ever be able to get right…

grimpixie, you read my mind. On the way home last night I was trying to come up with its phonetics, and eventually decided there was no way in hell I would be able to explain it here so that someone would be able to pronounce it.
Now, if Koos Kombuis was an SDMB member, then maybe.
Bootes…
If I remember my Dutch pronunciation correctly though, it’s not pronounced the same. It’s more like the vowel heard in the French word lune.
“U” can be a colloquial or humorous substition for “you”. I’ve just remembered that The Scaffold, the comic/musical group of Michael McCartney’s brother (yes, Sir Paul’s bro), had a hit in the early 1960s called “Thank U Very Much”. True, it’s not STandard English, but I think it qualifies as a word for the purpose of this thread.
