Ultimate origin

Pronunciation

  • IPA (Classical): [sʊsˈpɛk.tʊs], [sʊsˈpɛk.tuːs][1]
  • IPA (Ecclesiastical): [susˈpɛk.tus], [susˈpɛk.tus][1]

Forms

suspectus (feminine suspecta, neuter suspectum, comparative suspectior, superlative suspectissimus); first/second-declension adjective[2]

Etymology

The adjective is the perfect participle of suspiciō “to look up at; to suspect”, from sub “under” and speciō “to look”.[2][3][4] De Vaan traces ⟨speciō⟩ to Proto-Italic *spekje/o-, from Proto-Indo-European *speḱ- (“to look”).[5]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, of persons viewed with mistrust.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It meant viewed with mistrust, of doubtful character, suspected, as in Plautus and Cicero; believed without firm evidence, of dangers apprehended, as in Quintilian; and perhaps feeling mistrust, suspicious, as in Apuleius.[2] Festus remarked that it has different meanings, coming both from suspicor and suspiciō.[6]

Medieval Latin used it actively for anxious, distrustful.[7] English suspect (early 14th century, “under suspicion”) came through Old French suspect and directly from Latin.[4]

  • c. 250–184 BC – Plautus uses it.[2][3]
