With singular speed, furnish high-altitude gear
I believe the answer is:
spacesuit
'gear' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'with singular speed furnish high-altitude' is the wordplay.
I cannot really understand how this works, but
'singular' could be 's' (abbreviation sometimes used in dictionaries) and 's' is found in the answer.
'speed' could be 'pace' (pace is a kind of speed) and 'pace' is found in the answer.
The remaining letters 'suit' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for spacesuit that I've seen before include "Astronaut clothing" , "satellite outfit?" , "Astronaut's clothing" , "- "heavenly" outfit here?" , "Sealed garment worn by an astronaut" .)
