From Tolkien Gateway

gabil is a Khuzdul element only appearing the compound names Gabilgathol and Gabilān. As Gabilān is glossed as "great river",[1] and Gabilgathol is said to be have been translated into Belegost ("Great Fortress"),[2] one can, as Helge Fauskanger has suggested, infer that Gabil probably means "great".[3]
