U

Spanish Vowel

The Spanish letter U has some unique characteristics.

1. U is normally pronounced "oo."

Por ejemplo…

cuchara   spoon
usted   you (formal)
uno   one
champú   shampoo

2. In terms of syllable division, U is a weak vowel:

guasón   boring
aula   classroom

Note: When U diphthongs with other vowels, it sounds like an English W, which means that the letters cu followed by a vowel sound like qu in English.

cuidado   careful
cuando   when

3. In terms of consonant pronunciation, U is a
hard vowel
:

cuchara   spoon
mucho gusto   my pleasure

(a) Between G and a soft vowel, U is normally silent.

guisantes   peas
guía telefónica   phone book

Note: if U is to be pronounced, it needs a dieresis.

vergüenza   shame
lingüística   linguistics

(b) When a C or G needs to be pronounced "hard" in front of a soft vowel, the letter U plays a role – see hard and soft vowels

Please note that this explanation is only a guideline for the Spanish that I know, which is Castilian Spanish. There are many regional variations in Spanish pronunciation.
