Numbers one set out as most obtrusive (7)
I believe the answer is:
nosiest
'most obtrusive' is the definition.
Both the answer and definition are superlative adjectives. Perhaps they are linked in a way I don't understand?
'numbers one set out' is the wordplay.
'numbers' becomes 'nos' (no. is a kind of number).
'one' becomes 'I' (Roman numeral).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'set' with letters rearranged gives 'est'.
'nos'+'i'+'est'='NOSIEST'
'as' is the link.
Can you help me to learn more?
(Other definitions for nosiest that I've seen before include "Most snoopy" , "Most offensively curious" , "Most inquisitive" , "One sits (anag)" , "Most prying" .)
