Bride heartily made out after drinking liquor and conceived (8)
I believe the answer is:
imagined
'conceived' is the definition.
(I've seen this before)
'bride heartily made out after drinking liquor' is the wordplay.
'heartily' says to take the centre.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'after' is a charade indicator (letters next to each other).
'drinking' is an insertion indicator.
'liquor' becomes 'gin' (gin is a kind of liquor).
The middle letter of 'bride' is 'i'.
'made' with letters rearranged gives '[made]'.
'i'+'[made]'='i[made]'
'imaed' enclosing 'gin' is 'IMAGINED'.
'and' is the link.
(Other definitions for imagined that I've seen before include "Supposed" , "Visualised" , "Formed a mental picture" , "Dreamed" , "Envisaged" .)
