Completely taken by alphabetical statement of the obvious? (4,4,5)
I believe the answer is:
head over heels
'completely taken by' is the definition.
(as in being head over heels in love)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for head over heels that I've seen before include "normally upright?" , "Tumbling posture" , "Completely - turning as in a somersault" , "In great confusion (because of love?)" , "In disorderly haste" .)
