English luculent comes straight from the Latin adjective lūculentus, a derivative of lux (stem lūc-) “light,” from a very widespread Proto-Indo-European root leuk-, louk-, luk- “light, bright.” (The suffixed form leuktom becomes leuhtan in Germanic, lēoht in Old English, and light in English.) Latin lūculentus and English luculent are not much used in their literal senses but have a metaphorical sense like splendid and the colloquial British brilliant. Luculent entered English in the 15th century.

The adjective nummary comes straight from Latin nummārius “pertaining to coins or money,” a derivative of nummus (also nūmus), the name of several silver or gold coins. The Latin nouns come from noûmmos “current coin” in a western Doric Greek dialect spoken in southern Italy and Sicily and equivalent to Greek nómos “law, custom, something in customary or habitual use.” Nummary entered English in the early 17th century.

Chiefly British Slang. characterized by excessive elegance.
Pity that one doesn’t see as many lardy-dardy types as formerly—affected swells, languid fops, chichi dandies lounging about music halls and theaters. Lardy-dardy entered English in the 1850s, at the height of the Victorian era. It is often said to be the British aristos’ non-rhotic (“r-less”) Received Pronunciation of la-di-da—a nice story except that lardy-dardy predates la-di-da by nearly 20 years.
“Good afternoon!” — in rather lardy-dardy, middle-class English. “I wonder if I may see your things in your studio.”
It was exaggerated flattery he always felt provoked and disgusted with. Such absurd palaver, and lardy-dardy talk as that of his grand mover and seconder.
