New first lady wearing French article is odd (6)
I believe the answer is:
uneven
'odd' is the definition.
(thesaurus)
'new first lady wearing french article' is the wordplay.
'new' becomes 'n'.
'first lady' becomes 'eve' (I've seen this before).
'wearing' indicates putting letters inside.
'french article' becomes 'un' (French for 'a' - the indefinite article).
'n'+'eve'='neve'
'neve' going into 'un' is 'UNEVEN'.
'is' acts as a link.
(Other definitions for uneven that I've seen before include "Not uniform or smooth" , "Bumpy - odd" , "That's odd" , "Inconsistant in quality" , "Patchy" .)
