Diskette comes from cassette which had been used in photography long before describing tapes and just meant that it had a built in protective case.
The -ette in cassette and diskette is a diminutive suffix. Cassette means little box. Casse is French for box. And thus Diskette means little disk, not disk in a protective case. IBM introduced the term to mean floppy disks smaller than their 8” floppy disks

Cassette is a French word, diskette is not. It even says that in your links. IBM used the word for the 8in floppies too. It’s a portmanteau of disk and cassette because IBM already made hard drives and these were portable and looked a little like a photography cassette.
