Can I split noble into nob + the suffix -le?
-le is found in other adjectives such as little, brittle, fickle
nob is found in noble, nobleman, nobleness, nobler, noblesse, noblest, nobly. But pretty much all of these contain 'noble', so maybe noble is the root morpheme?
Note: 'nob' on its own is apparently a slang word for a rich person. So it carries a similar meaning as a noun. Except it's British and informal?
