Offspring; meditate (5)
I believe the answer is:
brood
This clue is a double definition.
'offspring' is the first definition.
(I've seen this before)
'meditate' is the second definition.
(brooding is a kind of meditating)
(Other definitions for brood that I've seen before include "Worry over" , "Think anxiously for some time" , "Ponder mournfully" , "Collection of chickens" , "Ponder - family" .)
