This papers aim to show how a poem can have an iconic meaning in addition to the literary or figurative meaning. When we say that a sign is iconic, we mean that the form of the sign reflects the meaning of the sign and that the form of the sign determines the meaning of the sign. A poem is the collection of literary words. The meaning of a poem can be determined depending on how its forms can be combined and which words the poet selects in his poem. This kind of meaning is the iconic meaning of the poem. I take the text-internal approach to show the iconic meaning of the poem. In other words, I closely focus on the forms consisting of a text, and then analyze the way these forms are combined in the text. To this end, chapter 2 deals with the nature of iconicity. Especially I look at the icon which is dealt with in the area of Charles Sanders Peirce's semiotics and principles of iconicity which are one of the subjects dealt with in cognitive linguistics. Section 3 examines at the way the iconic meaning in 'To Autumn' by Keats can be revealed. (Naval Academy)
