The origin of the lowercase letter v can be traced back to the Latin letter v. In ancient Rome, Latin letters were different in shape from modern letters. The letter v stands for vowel phoneme [u] and consonant phoneme [w]. With the passage of time, the shape and usage of the Latin letter V became the phoneme representing the vowel U, and the letter U appeared. The modern lowercase letter V evolved from the Latin letter V in Roman times.
