NAIROBI: Every writer is taught to show instead of telling. One way writers are taught to do this is by use of imagery, which consists of metaphors and similes. If you read say, Things Fall Apart, you will see that Chinua Achebe employs imagery from the outset as he describes the fight between Okonkwo and Amalinze the cat, painting a clear mental picture that transports the reader to this fictional village of Umofia before the missionaries and as such the colonialist arrived.
