alto

The word "alto" entered English in the late 16th century from Italian, where it served as a musical term. It is a shortening of the phrase "alto canto," meaning "high song," derived from the Latin altus, meaning "high." Ironically, in modern choral music, "alto" refers to the lowest female voice, a semantic shift that occurred because the part was originally sung by high male voices (countertenors), which were considered "high" relative to the standard tenor. Thus, the term retains its literal link to height but applies it within a shifted frame of vocal reference.

Structure: alt (high) + o (suffix) - alt: From Italian, from Latin altus (high, deep). In this word, it denotes the high vocal range relative to other male voices. - o: A common Italian masculine noun ending, adopted into English to signify the word's origin and category.
