Etymology

It is from ex- “out” and pandō “to spread”.[2][1][3] Its participle is ⟨expassum⟩, as in Caecilius, or ⟨expānsum⟩, as in Pliny the Elder and Gellius.[2][4]

Earliest recorded meaning

The OLD's earliest citation is from Caecilius, of spreading out.[2] Köbler dates Caecilius 230/220–168 BC.[5]

Semantic evolution

It meant to spread out, unfold, as Pliny the Elder's clothes spread over a cold spring, and in Seneca to become wider, expand.[2][6] In Lucretius it meant to expound, unfold in words.[2]

In Ecclesiastical Latin it meant to stretch, spread out.[7] It survives in Italian spandere and French épancher, and Anglo-French espaundre and Old French espandre with the Latin gave English expand in the early 15th century.[1][3]
