Semi-demi-hemi-quiver-quaver origin

No. IIRC from my music theory study, the original note was the breve, which is now eight of today’s notes. The minim (two notes) came next, then the crotchet - one note. Half a note is a quaver, a quarter is a semiquaver, an eighth is a demisemiquaver, and a sixteenth is a hemidemisemiquaver.
