Standing stone tops American tours regularly (6)
I believe the answer is:
status
'standing' is the definition.
(I've seen this before)
'stone tops american tours regularly' is the wordplay.
'stone' becomes 'st' (abbreviation).
'tops' says to take the initial letters.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The first letter of 'american' is 'a'.
The alternate letters of 'tours' are 'tus'.
'st'+'a'+'tus'='STATUS'
(Other definitions for status that I've seen before include "Rank or standing in society" , "Situation as it was before" , "Social or professional standing" , "and 9: Existing state of affairs" , "legal position" .)
