Function boring girl in charge of stars (8)
I believe the answer is:
galactic
'function boring girl in charge of stars' is the definition.
I can't tell whether this defines the answer.
'function boring girl in charge of' is the wordplay.
'function' becomes 'act' (I've seen this before).
'boring' indicates putting letters inside (some letters must 'bore' a hole into other letters).
'girl' becomes 'gal' (synonyms).
'in charge of' becomes 'ic'.
'gal'+'ic'='galic'
'act' inserted inside 'galic' is 'GALACTIC'.
Can you help me to learn more?
(Other definitions for galactic that I've seen before include "Relating to, eg, the Milky Way" , "More than stellar" , "To do with large independent systems of stars" , "Relating to large star systems" , "Of large independent system of stars" .)
