US agency stricken as administrator hides (4)
I believe the answer is:
nasa
'us agency' is the definition.
The definition suggests a singular noun which matches the answer.
'stricken as administrator hides' is the wordplay.
'hides' says the answer is hidden in the clue.
'NASA' can be found hidden inside 'stricken as administrator'.
Can you help me to learn more?
(Other definitions for nasa that I've seen before include "US headquarters for space exploration" , "rocket launcher" , "US agency responsible for space flight" .)
