Ambiguity Continued

Ambiguity- 
Multiple meaning; the allowance of overtone and connotation by context.

1. The detail is effective in several ways at once, creating comparisons with several points of likeness or difference within one aspect.
2. Two or more alternate meanings resolved into one; alternate meanings combine.
3. Two apparently unconnected meanings are given simultaneously.
4. A fortunate confusion; or unresolved details that force the reader to interpret what cannot be fully explained by the text.

Discussion:
