U \
U \ ([=
u ]),
the twenty -
first letter of the English alphabet ,
is a cursive form of the letter V ,
with which it was formerly used interchangeably ,
both letters being then used both as vowels and consonants .
U and V are now ,
however ,
differentiated ,
U being used only as a vowel or semivowel ,
and V only as a consonant .
The true primary vowel sound of U ,
in Anglo -
Saxon ,
was the sound which it still retains in most of the languages of Europe ,
that of long oo ,
as in tool ,
and short oo ,
as in wood ,
answering to the French ou in tour .
Etymologically U is most closely related to o ,
y (
vowel ),
w ,
and v ;
as in two ,
duet ,
dyad ,
twice ;
top ,
tuft ;
sop ,
sup ;
auspice ,
aviary .
See {
V },
also {
O }
and {
Y }.
