Pronunciation
Forms
coniectō (present infinitive coniectāre, perfect active coniectāvī, supine coniectātum); first conjugation[1] Suetonius has the spelling coiect-.[2]
Etymology
It is the frequentative of coniciō “to throw together; to conclude”, with -tō, from con- and iaciō “to throw”.[2][3][1] De Vaan traces ⟨iaciō⟩ to Proto-Italic *jak-i- (“to throw”), from Proto-Indo-European *(H)ih₁-k- (“to throw, let go”), cognate with Ancient Greek ἵημι (híēmi, “to send, throw”).[4]
Earliest recorded meaning
The OLD's earliest citation for inferring is Cicero.[2] Köbler dates Cicero 81–43 BC.[5]
Semantic evolution
Lewis & Short call it ante-classical and then not found again until Livy in its physical sense, to throw or bring together, as in a decree of Tiberius Gracchus quoted by Gellius.[6][7] In Cicero and later it meant to infer, conclude, conjecture, guess, and to interpret, as of dreams and omens.[2][6]
It survives as Catalan congitar.[1]
