The letter U is an interesting beast. Both of English's main parent languages, Latin and German, use it differently than English does. Latin turns V into a vowel that's almost but not quite U. German does strange things to the sound. English keeps things simple, yet U is by far the rarest of the English vowels, 13th in overall frequency. That may be clear in the following U word for kids lists: sometimes words may be trickier or more obscure than expected, simply because only so many words start with U. Follow useful lists of U words for kids from preschool through to the 5th grade.
