Latin filum and filius

Still no takers, eh, BMO? Well, this is English Forums, not Latin Forums. I got as far as identifying the former as a neuter noun and the latter as a masculine noun, and found no references relating the two in any way. A sort of negative evidence, I suppose. . . .

I thought I could explain son is related to thread as both are all "lineages;" and filum and filius do look alike. Thanks.

I imagine they are related somehow. I'm sorry I can't help anymore but classical language isn't one of my fortes... I got into a argument once with my teacher. He said the english word 'bath' didn't come from the greek 'bathos' meaning deep. I'm sure I was right.

Unfortunately, RJ, even though the modern spelling is similar, the word origins are not the same: 'bath' has a Germanic origin in batham, through Old High German baen to warm and Old English bæth, according to Oxford and Webster.

Hello BMO

'Filum' (thread) < 'figlum' < 'figo' (I fix/fasten)
[cognate with Greek 'sphingô', I bind tight]

'Filius' (son) [cognate with Greek 'phuô', I bring forth, I engender]

Ah, at last! Thank you, Mr. P.
