Badly carves some smiling emojis in crack in glacier (8)
I believe the answer is:
crevasse
'crack in glacier' is the definition.
'crevasse' can be an answer for 'crack' (crevasse is a kind of crack). I am not sure about the 'in glacier' bit.
'badly carves some smiling emojis' is the wordplay.
'badly' is an anagram indicator.
'some' indicates taking the first letters.
The first letters of 'smiling emojis' is 'se'.
'carves' is an anagram of 'crevas'.
'crevas'+'se'='CREVASSE'
'in' is the link.
Can you help me to learn more?
(Other definitions for crevasse that I've seen before include "Deep glacial fissure" , "big split" , "cold break" , "Crack in a mountain slope or a glacier" , "climbing hazard in glacier" .)
