IPA: /kæˈdjuːkəs/
KK: /kæˈdjuːkəs/
Referring to something that falls off or sheds early in its development, like certain plant parts or the gills of amphibians.
The caducous leaves of the plant fell off before winter.
Caducous is derived from the Latin "caducus" (meaning falling or perishable) and the suffix "-ous" (meaning full of or possessing). The word describes something that is prone to falling or is temporary in nature.
Think of something that is 'falling' or 'perishable' — that's what caducous means, as it refers to things that are not permanent.
