One alternative is small letters, which accurately describes the size of the letters in relation to their capital counterparts. Another option is minuscule, which comes from the Latin word minusculus meaning "rather small." Lowercase can also be substituted with smalls or little letters, both of which capture the diminutive size of the alphabet characters. In summary, while lower case is the most commonly used term, there are several other synonyms available that accurately describe this writing style.
