Females endlessly grabbing attention is fatiguing (9)
I believe the answer is:
wearisome
'fatiguing' is the definition.
(thesaurus)
'females endlessly grabbing attention is' is the wordplay.
'females endlessly' becomes 'wome' (I can't justify this - if you can you should believe this answer much more).
'grabbing' indicates putting letters inside.
'attention' becomes 'ear' (having someone's ear is having their attention).
'ear'+'is'='earis'
'wome' enclosing 'earis' is 'WEARISOME'.
Can you help me to learn more?
(Other definitions for wearisome that I've seen before include "Boring" , "pestilential" , "Vexatious" , "Tedious, tiring" , "Trying" .)
