What does cascade mean?
A cascade is a small waterfall, especially one that descends over rocks in a series of steps or tiers, though the word is just as often used figuratively to describe anything that pours or arrives in a continuous, rushing flow — a cascade of golden hair, a cascade of letters, a cascade of failures. As a verb, to cascade means to fall or move downward in this way, frequently with 'down' or 'over'. The word derives from the Italian cascata, meaning 'fall', and entered English in the seventeenth century. It shares its root with everyday words such as casual and occasion, all tracing back to Latin cadere, 'to fall'. Cascade tends to sound graceful and evocative where 'waterfall' sounds plain, and its figurative uses convey momentum and abundance: events that trigger further events are said to have a cascading effect, a sense widely used in science, economics, and computing.
A small waterfall, typically one of several descending in stages; more broadly, any continuous, rushing flow or outpouring of something.
"A cascade of blossoms tumbled over the old garden wall each spring."
Often used figuratively with 'of': a cascade of applause, a cascade of emails.
To fall or pour downward rapidly and continuously, or to arrange or occur in a series of successive stages.
"Her long red hair cascaded down her back as she turned."
Usually takes a directional particle such as 'down', 'over', or 'from'.
The plural commonly refers to multiple waterfalls or to repeated instances of the figurative sense.
"The river's upper course is broken by a series of cascades and rapids."
Cascade comes straight from Italian cascata — 'to fall' — which is why English also borrowed the same root for words like casual and occasion: things that simply befall you.

Etymology of cascade
Cascade was borrowed into English in the early seventeenth century from French, ultimately from the Italian cascata, meaning 'a fall', derived from cascare, 'to fall', itself from Vulgar Latin based on Latin cadere. The same Latin verb gives English cognates such as casual, occasion, and cadence, all originally connected to the idea of falling or happening. The word has referred to small stepped waterfalls since its adoption, with the figurative and verbal senses developing later.
