Surface Forms

viaduct singular
viaducts plural

Morphology

viaduct = duct (semi-transparent) = via + duct

Both combining forms are recognizable ('via' = by way of; 'duct' = channel), but learners may not predict the specific structural sense 'bridge for a road' and 'duct' can suggest a tube rather than a bridge. [Postprocessing: moved 'via' from base_words to prefix]

Etymology

Viaduct comes from the Latin parts via 'road' and duct 'to lead', the same 'duct' you see in 'air duct' or 'aqueduct'. So a viaduct is a bridge that 'leads' a road or railway across low ground, which is why it means a long bridge with many spans.
