From Nitid to Nitidity

Nitid (adjective):  bright; lustrous.

    The noun, nitidity, is pronounced with the emphasis on the second syllable.  (How I love Dictionary.com!)

    But I’m not sure I love nitidity.  It reminds me too much of nits and lice outbreaks at preschools. 

    So it may be awhile before I can use nitid or nitidity in any writing.  First, I need to be cured of the lousy connotation.
