Meteor is out of the ordinary in a boring way (8)
I believe the answer is:
tiresome
'ordinary in a boring way' is the definition.
'tiresome' can be an answer for 'ordinary' (thesaurus). I am not sure about the 'in a boring way' bit.
'meteor is out of' is the wordplay.
'out of' indicates anagramming the letters.
'meteor'+'is'='meteoris'
'meteoris' anagrammed gives 'TIRESOME'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for tiresome that I've seen before include "irritating" , "Aggravating" , "Wearying" , "Boring, irksome (colloq.)" , "Boring, annoying" .)
