Etymology

It is from intrō (“inside”) and dūcō “to lead”; manuscripts sometimes split it as ⟨intrō dūcō⟩.[2][1][3]

Earliest recorded meaning

The OLD's first citations are from Plautus, as his bringing in of a gang of slaves for sale.[2][4] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant to lead or bring in, introduce into a place, as Sallust's soldiers brought in by night, to usher someone into another's presence, as in Ennius, to bring onto the stage, and in law to put in possession.[2][4] It meant to insert into a speech or book, to bring forward a subject or theory, and to establish a custom, as in Cicero; in Gaius it meant to start an action at law.[2]

In Ecclesiastical Latin it meant to introduce, bring in.[6] It survives in French introduire, Italian introdurre and Spanish introducir.[1] English introduce was borrowed in the early 15th century.[3]
