A figure of speech in which an implied comparison is made between two unlike things that actually have something in common. A metaphor expresses the unfamiliar (the tenor) in terms of the familiar (the vehicle). When Neil Young sings, "Love is a rose," "rose" is the vehicle for "love," the tenor. (In cognitive linguistics, the terms target and source are roughly equivalent to tenor and vehicle.)
Types of Metaphors: absolute, complex, conceptual, conventional, creative, dead, extended, grammatical, mixed, primary, root, submerged, therapeutic, visual
Life is a rollercoaster
Her voice was music to his ears
You are the light in my life
He's the sun in my butt
love is a lie
my name is earl
the sky is green
friends are a shadow
the cat was snow
her hair was coal
life is a rainbow
