Forms
perplexus (feminine perplexa, neuter perplexum); first/second-declension adjective[1]
Etymology
It is the participle of an unattested compound ⟨*perplectō⟩, from per- (“through”) and plectō (“to plait, twine”).[2][3][1] De Vaan traces plectō to Proto-Italic *plekt- and Proto-Indo-European *pleḱ-t-e/o- (“to plait, twine”), with cognates such as Ancient Greek πλέκω (plékō, “to braid, twine”) and Old High German flehtan (“to plait”).[4]
Earliest recorded meaning
Köbler dates it from Plautus,[5] who in the Miles gloriosus has a character ask what madness makes the other call him by a wrong, muddled name.[2] De Vaan dates the adjective from Lucretius.[4]
Semantic evolution
It means entangled, intertwined: Lucretius has atoms hampered by their own entangled shapes,[2][6] Virgil the tangled path of a wood,[6] and the Vulgate entwined sinews in Job.[6] Figuratively it is complicated and hard to sort out: in Livy envoys say they do not know what is complicated about their embassy, since they have come simply to ask for friendship,[2] and Livy calls a prophetic poem obscure, not only because the future is uncertain but also more puzzling in its kind of writing.[2] Lewis & Short note it is not in Cicero or Caesar.[6] The English perplex comes from it, through the earlier adjective perplex.[7]
Timeline
- c. 250–184 BC – Plautus of a muddled name.[2][5]
- 96–55 BC – Lucretius of entangled atoms.[2][6][4]
- 70–19 BC – Virgil of a tangled path.[6]
- 59 BC–17 AD – Livy of a cryptic poem.[2]
- late 14th century – The English adjective perplex appears; the verb perplex follows in the 1590s.[7]
