From Proto-Italic *fēlājō, from earlier Proto-Italic *θēlājō, from Proto-Indo-European *dʰeh₁(i)-l-éh₂-ye-ti, from Proto-Indo-European *dʰeh₁(y)- (“to suck, suckle”). Cognates include Sanskrit धयति (dhayati), Ancient Greek θηλή (thēlḗ), Gothic 𐌳𐌰𐌳𐌳𐌾𐌰𐌽 (daddjan, “suckle”), and Old Church Slavonic доити (doiti). Related to fēmina, fīlius, fētus.
Uncertain; one common hypothesis is a borrowing from Frankish *falljō.
A derivation from fel (“bile”) has also been suggested (said by the Oxford English Dictionary to be “the most probable”).
A third hypothesis is a derivation as an obscene term of abuse from the verb in 'Etymology 1'.
Third-declension noun.
