head over heels

I'm a little stuck... Click here to teach me more about this clue!

'completely taken by' is the definition.

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" .)
