Fascinating! Well, to me anyway… 
[quote author=anders link=board=etymology;num=1104055484;start=0#5 date=12/29/04 at 19:54:28]Believe it or not, but the *mêlon is a linguistic apple. The Linnaeus apple is Pyrus malus. The oldest attested form is Hittite mahla ‘grapevine, branch’. Not necessarily PIE; might have been borrowed from/originated in a Mediterranean languge.
Wow! So, not related at all…?
anders:
PIE *mel- ‘a limb’ > Gr. melos ‘limb’; hence a musical member or phrase, hence music, song, melody.
Which would have been related to that grapevine…
anders:
Another *mel- is ‘of a darkish colour’, giving Gr. melâs ‘black. Compare Herr Philipp Schwarzerd > Melanchthon.
Which sounds logically connected (in the European/Western mind) to the concept of bad (dark = bad).
anders:
And yes, ‘melt’ and ‘mild’ are yet another *mel-: ‘soft etc.’
Hence, mellow, I take it…
anders:
A fifth *mel- is responsible for Lat. malus ‘bad and male ‘ill’.
As a natural development of the dark->bad evolution.
Hmm…
