What is "topicality"

n. The condition of being topical.

n. the attribute of being of interest at the present time; "the library had to discard books that had lost their topicality"

Topicality is a stock issue in policy debate which pertains to whether or not the plan affirms the resolution as worded. To contest the topicality of the affirmative, the negative interprets a word or words in the resolution and argues that the affirmative does not meet that definition, that the interpretation is preferable, and that non-topicality should be a voting issue.
