Initially high above -- float there? (5)

I believe the answer is:

hover

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

'float there?' is the definition.
'hover' can be an answer for 'float' (I've seen this before). I am not certain of the 'there?' bit.

'initially high above' is the wordplay.
'initially' says to take the initial letters.
'above' becomes 'over' (I've seen this before).
The initial letter of 'high' is 'h'.
'h'+'over'='HOVER'

Can you help me to learn more?

(Other definitions for hover that I've seen before include "Wait around (like a kestrel)" , "Be stationary in the air" , "Stay near" , "Remain suspended" , "Low flying machine (10)" .)

I've seen this clue in The Telegraph.
