Embrace worries son (6)
I believe the answer is:
caress
'embrace' is the definition.
(I've seen this before)
'worries son' is the wordplay.
'worries' becomes 'cares' (I've seen this before).
'son' becomes 's' (genealogical abbreviation for son).
'cares'+'s'='CARESS'
(Other definitions for caress that I've seen before include "Stroke fondly" , "Stroke affectionately" , "Tenderly stroke" , "Expression of affection" , "Stroke lovingly" .)
