Simile:
Simile is a figure of speech that uses like, as, or as if to compare two essentially different objects, actions, or attributes that share some aspect of similarity. In contrast to a Metaphor, in which a comparison is implied, a simile expresses a comparison directly.
Examples of Simile:
-Here and there
his brown skin hung in strips
like ancient wallpaper..
--Elizabeth Bishop
An old man whose black face
shines golden-brown as wet
pebbles under a street light...
--Denise Levertow
Like a small grey
coffe-pot
sits the quirrel
--Humbert Wolfe
