There's one good reason why there are so many adjectives that start with the letter "R;" English speakers really like the letter.
The thing about adjectives that start with R is that most of them start with "re." You can add "re" to so many things that you can make an extremely long list of R adjectives.
You can make as many adjectives that start with R as there are verbs in the English language. Can a dog be rewalked? Can a governor be recalled? Sure! In this world, anything's possible.
Of course, "re" doesn't always mean again. "Re" can also mean back or behind. For example, these adjectives are all founded on the basis that "re" has something to do with back or behind:
Gene Autry's super hit, the timeless Rudolph the Red-nosed Reindeer, has pervaded the Christmas season so thoroughly that children who have never seen a real reindeer think that their noses are indeed red. That is one active little R adjective!
Why would you want to say goodbye to "Ruby Tuesday"? The Rolling Stones' hugely successful song rests on an R adjective. Their name does, too, taken from another song: Bob Dylan's "Like a Rolling Stone."
Songs do well with R's. "Red, red wine," "Raspberry Beret," "Rainy Day Woman," and countless others all have used them to great result on a global level.
Have you ever wondered why contestants in the television game show Wheel of Fortune are given the letters R, S, T, L, N, and E when they're crunched on time?

Here are more examples:
No matter how many times a machine can calculate and recalculate, they will never be able to understand why human beings love R's so much, but clearly, they do. Perhaps it has something to do with an atavistic urge to sound animalistic. Maybe man has not been rightly removed from his residual roaring desire. His reverberating response, transcending rough regional roads, cannot be redacted or restrained; it is resilient, and it starts with the letter R!
