airstrip

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

'whereon one could be earthbound?' is the definition.
I can't judge whether this definition defines the answer.

'voices tense epitaph' is the wordplay.
'voices' becomes 'airs' (I've seen this before).
'tense' becomes 't' (abbreviation used in many dictionaries).
'epitaph' becomes 'RIP' (rest in peace).
'airs'+'t'+'rip'='AIRSTRIP'

Can you help me to learn more?

(Other definitions for airstrip that I've seen before include "Temporary runway" , "From which you might take off" , "(Unprepared) runway" , "A plane lands on it" , "Small runway" .)
