The name for a flowery expression - not a cliché [closed]

Solution 1:

The year 19 ʙᴄ’s twin gifts urbi et orbi

It was during the eighth year of the reign of Caesar Augustus, that selfsame year in which Agrippa completed his great Aqua Virgo, when Horace sent as an epistle to the consul Piso the poem we have come to call the Ars Poetica, whose lines 14–21 contain history’s first mention of purple prose. There Horace writes that

Important incipits
full of profound professions
see often the purple patch
or two, broadly resplendent,

applied to them.

As Agrippa’s aqueduct would prove a font rich enough to sustain the Eternal City in all the ages since, so too would the ageless wisdom of Horace’s poem come to inspire writers of the world even unto our own day. If only they had read more closely! :)

Hackneyed phrases and tired refrains

Unlike what several other posters seem to feel, I hold that the various expressions you mention are not the flowery language of purple prose. They are not unrelated, fanciful language used to beautify simple passages to make these more attractive to bored readers, yet which nonetheless serve mostly to distract with their long-winded discursions into matters unrelated to the one at hand.

On the other hand, the opening section of this post which you have just done me the honor of reading might be said to be an example of “purple prose”, but I do not believe that this is the sort of thing that you are referring to at all.

Rather, yours are overwrought expressions repeated so often that our ears tire of hearing them. They are like the repeated refrain of an old familiar tune which the entire room sings along to in mindless unison, words that everyone knows and has heard so often before than no thought need be paid to their automatic repetitions.

For this reason, I believe that hackneyed is the best word to describe the sort of annoyingly repetitious phrases you have listed. The website World Wide Words discusses the origin of this word and its evolution into extended uses in an article that includes the following text, with bold emphasis mine:

Horses of the hackney type were often worked heavily, in the nature of things that were hired out to all and sundry. So the word evolved in parallel with the previous sense to refer figuratively to something that was overused to the point of drudgery. By the middle of the sixteenth century, hackney was being applied to people in just this sense, and was abbreviated about the start of the eighteenth century to hack, as in hack work; it was applied in particular to literary drudges who dashed off poor-quality writing to order — hence its modern pejorative application to journalists.

Hackney horses were also widely available and commonly seen, to the extent that they became commonplace and unremarkable. So yet another sense evolved — for something used so frequently and indiscriminately as to have lost its freshness and interest, hence something stale, unoriginal or trite. The adjective hackneyed communicated this idea from about the middle of the eighteenth century on.

The annoying and pretentious business jargon that Forbes rants against is the same sort of thing: overused clichés (a cliché need involve no metaphor) that people keep mindlessly repeating:

The next time you feel the need to reach out, touch base, shift a paradigm, leverage a best practice, or join a tiger team, by all means do it. Just don't say you're doing it.

Hackneyed refrains like those in your list or the ones in Forbes’ drive the people who notice them stark-raving crazy while adding nothing to the writing. Good writers avoid them like the plague._😜
