See this crossing the sky or meet it broken on top of earth (9)
I believe the answer is:
meteorite
'see this crossing the sky' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'or meet it broken on top of earth' is the wordplay.
'broken' indicates an anagram.
'on' means one lot of letters goes inside another (as in clothing 'on' a person).
'top of' says to take the initial letters.
The first letter of 'earth' is 'e'.
'meet'+'it'='meetit'
'meetit' with letters rearranged gives 'meteit'.
'or' placed inside 'meteit' is 'meteorit'.
'meteorit'+'e'='METEORITE'
Can you help me to learn more?
(Other definitions for meteorite that I've seen before include "Something falling from the sky" , "Matter in the solar system that reaches earth" , "Piece of fallen star" , "Piece of rock fallen from outer space" , "Lump from space" .)
