Endless large ice formation? (7)
I believe the answer is:
glacier
'endless large ice formation?' is the definition.
'glacier' can be an answer for 'formation?' (glacier is a kind of formation). I'm not certain of the 'endless large ice' bit.
'endless large ice formation?' is the wordplay.
'endless' means to remove the last letter.
'formation?' is an anagram indicator (I've seen 'formation' mean this).
'large'+'ice'='largeice'
'largeice' with its last letter removed is 'largeic'.
'largeic' anagrammed gives 'GLACIER'.
Can you help me to learn more?
(Other definitions for glacier that I've seen before include "Mass of ice moving down a mountain" , "Slow-moving flow of ice" , "Large flow of ice" , "Flowing ice sheet" , "River of ice" .)
