thnksWhat does the literary term Controlling metaphor mean? could u give an example also from a piece of literature
A controlling metaphor or conceit runs through an entire work and determines the form or nature of that work. An example might be John Donne's ';The Flea';





The term is generally associated in contemporary usage with the 17th century metaphysical poets. In the metaphysical conceit, metaphors have a much more purely conceptual, and thus tenuous, relationship to the thing being compared. Helen Gardner[2] observed that ';a conceit is a comparison whose ingenuity is more striking than its justness.';... a comparison becomes a conceit when we are made to concede likeness while being strongly conscious of unlikeness.'; An example of the latter would be George Herbert's ';Praise (3),'; in which the generosity of God is compared to a bottle which (';As we have boxes for the poor';) will take in an infinite amount of the speaker's tears.





An often-cited example of the metaphysical conceit is the metaphor from John Donne's ';The Flea,'; in which a flea that bites both the speaker and his lover becomes a conceit arguing for the depth of their union:





Oh stay! three lives in one flea spare


Where we almost, yea more than married are.


This flea is you and I, and this


Our marriage-bed and marriage-temple is.What does the literary term Controlling metaphor mean? could u give an example also from a piece of literature

Simile

Note the use of the word ';as'; in the comparison.
