Like a bog containing first of daffodils (6)
I believe the answer is:
admire
'like' is the definition.
(I've seen this before)
'a bog containing first of daffodils' is the wordplay.
'bog' becomes 'mire' (I've seen this before).
'containing' means one lot of letters goes inside another.
'first of' says to take the initial letters.
The first letter of 'daffodils' is 'd'.
'a'+'mire'='amire'
'amire' enclosing 'd' is 'ADMIRE'.
(Other definitions for admire that I've seen before include "Respect (someone)" , "Esteem. value" , "put on a pedestal" , "Respect greatly" , "Dig" .)
