THE RIGHT WORD
Wildflowers might be prevalent in
the mountains during the spring months, but a particular type of wildflower
might be the prevailing one. Prevalent, in other words, implies
widespread occurrence or acceptance in a particular place or time (: a
prevalent belief during the nineteenth century), while prevailing suggests
that something exists in such quantity that it surpasses or leads all others in
acceptance, usage, or belief (: the prevailing theory about the evolution of
man).
Wildflowers might also be abundant
in the valleys—a word that, unlike prevalent and prevailing,
is largely restricted to observations about a place and may suggest oversupply
(: an abundant harvest; indications of decay were abundant).
