Take drugs to get up? That's uncannily weird! (5)
I believe the answer is:
eerie
'uncannily weird' is the definition.
'eerie' can be an answer for 'weird' (both can mean strange or unsettling). I am not certain of the 'uncannily' bit.
'take drugs to get up? that's' is the wordplay.
'take' becomes 'r' (abbreviation for 'recipe', Latin for 'take').
'drugs' becomes 'ee' (an abbreviation for ecstasy written twice).
'to get up?' says the letters should be written backwards (I've seen 'getting up' mean this).
'that's' becomes 'ie'.
'r'+'ee'='ree'
'ree' reversed gives 'eer'.
'eer'+'ie'='EERIE'
Can you help me to learn more?
(Other definitions for eerie that I've seen before include "Awesome" , "Weird, uncanny" , "Strangely frightening" , "Spooky, supernatural" , "Bloodcurdling" .)
