Finding the correct word in English

Speaking with our Dutch student recently has brought home to us how intricate learning the English language is.
My Father was telling me yesterday that in the second world war, it was possible to tell spys in conversation as they did not have the subtle nuances familiar to an Englishman.

There are so many words to describe rain, and an English person knows when a foreign person is using the incorrect word! - mizzling, dripping, pouring, thrashing, chucking, throwing, bucketing, torrential, fine mist, raining cats and dogs, and so on.
Presumably the English have lots of words to describle rain because we have lots of rain to describe!

Song For The Rainy Season by Elizabeth Bishop

Hidden, oh hidden
in the high fog
the house we live in,
beneath the magnetic rock,
rain-, rainbow-ridden,
where blood-black
bromelias, lichens,
owls, and the lint
of the waterfalls cling,
familiar, unbidden.

In a dim age
of water
the brook sings loud
from a rib cage
of giant fern; vapor
climbs up the thick growth
effortlessly, turns back,
holding them both,
house and rock,
in a private cloud.

At night, on the roof,
blind drops crawl
and the ordinary brown
owl gives us proof
he can count:
five times--always five--
he stamps and takes off
after the fat frogs that,
shrilling for love,
clamber and mount.

House, open house
to the white dew
and the milk-white sunrise
kind to the eyes,
to membership
of silver fish, mouse,
bookworms,
big moths; with a wall
for the mildew's
ignorant map;

darkened and tarnished
by the warm touch
of the warm breath,
maculate, cherished;
rejoice! For a later
era will differ.
(O difference that kills
or intimidates, much
of all our small shadowy
life!) Without water

the great rock will stare
unmagnetized, bare,
no longer wearing
rainbows or rain,
the forgiving air
and the high fog gone;
the owls will move on
and the several
waterfalls shrivel
in the steady sun.
