The treble clef is also known as the G clef. The reason it is called the G clef is because the spiral at the beginning of the clef wraps around the second line, which is the G line on the staff. This spiral helps to indicate that the note G is on that line and helps to orient musicians when reading sheet music. To find this answer, you can do a simple search on any search engine using keywords such as "treble clef alternative name" or "G clef definition."
