Etymology

It is probably inherited from Proto-Italic *pusl-, inherited from Proto-Indo-European *plus- (“flea”), with the consonants transposed:[2][3][1] ⟨pūl-⟩ would go back to ⟨*pusl-⟩, from ⟨*plus-⟩.[2][3] The ending is the one also seen in cīmex (“bug”) and culex (“gnat”).[3][1] De Vaan notes that the words for “flea” in the various languages seem to belong together but that no single preform can be reconstructed, since taboo and folk etymology often reshape the names of insects.[2]

Cognate with Sanskrit प्लुषि (plúṣi-), Ancient Greek ψύλλα (psúlla), Old Armenian լու (lu), Albanian plesht, Lithuanian blusà, Czech blecha and Old High German flōh, all meaning “flea”.[2][1]

Earliest recorded meaning

De Vaan and Köbler date it from Livius Andronicus.[2][4] Plautus uses it too.[5][6]

Semantic evolution

Besides the flea, Columella and Pliny the Elder use it of a small creature that eats young plants, the earth flea.[7][5][6]

British Medieval Latin glossaries give it with Old English flaeh, and it was used in phrases and figures, and in allusions to the flea of the first Book of Kings.[8] Herba pūlicum was fleawort.[8]
