Pronunciation

Forms

suspect (feminine suspecte, masculine plural suspects, feminine plural suspectes)[1] First suspet (1311), remade as suspect about 1360.[2][3][4] Old French also had the more popular forms sozpis and suspiz (13th century).[5][2]

Etymology

It is borrowed from Latin suspectus (“suspected, suspicious”),[5][2][6][7][1] the past participle of suspiciō (“to look up at, to suspect”),[5][2][3] a sense of “suspect” that is very rare in Latin, where the deponent suspicor usually carried it.[5] The verb is formed from sub- (“under”) and the archaic speciō (“to look”), seen in many compounds;[2][4] Rey traces it to an Indo-European root Proto-Indo-European *spek- (“to observe”), also seen in the Germanic verb for “to observe” that gave épier1 and espion.[2] The old popular forms sozpis and suspiz have a counterpart in Old Occitan sospeit (1200).[5][2]

Littré compares Walloon suspek, Spanish suspecto, Portuguese suspeito and Italian sospetto.[8]

Earliest recorded meaning

The first record (1311, as suspet, in the cartulary of Ponthieu) applies it to a thing that arouses suspicion.[5][2] Applied to people, “whose conduct invites suspicion”, it appears in 14th-century manuscripts such as the Enseignement d'Aristote.[5]

Semantic evolution

The adjective has applied from the start both to a suspected person and to a thing that inspires distrust.[2] Suspect de is used of a person who might be guilty of something (1636, Monet) or of a thing that seems to hide something blameworthy (1682).[2][5] By extension it described a thing of doubtful value (1669) and especially food or goods without sufficient guarantees (1694);[2] in medicine a wound suspecte was thought to be infected (1572, Paré), and the Académie recorded lieu suspect de contagion in 1694.[5]

During the Revolution it was used of people whom the authorities feared would act against them (hommes suspects à la Nation, 1789), and as a noun from 1793, notably in the Loi des suspects voted by the Convention on 17 September 1793.[5][2] In the 19th century it came to mean a person whom the police consider a possible culprit (about 1850), and in the 20th century it is often a noun in this sense.[2]
