Suitably seated with decorum (6)
I believe the answer is:
sedate
'suitably seated with decorum' is the definition.
I can't judge whether this definition defines the answer.
'suitably seated with decorum' is the wordplay.
'seated' anagrams to 'SEDATE'.
However, I am not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for sedate that I've seen before include "Staid - teased (anag)" , "Staid and sober" , "Calm - staid" , "Administer a calming drug" , "Calm and demure" .)
