[Sniper]

are there any words which share the same root?because it is the first time i hear 'φελγ-'

[akritas]

No I dont have any other information as about this root. I dont know if the correct root is fel(φελ-) because with the specific root we have a lot of examples like.....

fellos-φελλός-cork
felefs-φελλεύς-stony ground
fellinos-φελίνος-made of cork
