simile

simile (sĭm`əlē) [Lat.,=likeness], in rhetoric, a figure of speech in which an object is explicitly compared to another object. Robert Burns's poem "A Red Red Rose" contains two straightforward similes:

My love is like a red, red rose
  That's newly sprung in June:
My love is like the melody
  That's sweetly played in tune.

The epic, or Homeric, simile is an elaborate, formal, and sustained simile derived from those of Homer.

simile

Figure of speech involving a comparison between two unlike entities. In a simile, unlike a metaphor, the resemblance is indicated by the words “like” or “as.” Similes in everyday speech reflect simple comparisons, as in “He eats like a bird” or “She is slow as molasses.” Similes in literature may be specific and direct or more lengthy and complex. The Homeric, or epic, simile, which is typically used in epic poetry, often extends to several lines.
