Ghastly new tangles from end to end (10)
I believe the answer is:
lengthways
'end to end' is the definition.
I can't tell whether this definition defines the answer.
'ghastly new tangles' is the wordplay.
'tangles' is an anagram indicator (I've seen 'tangled' mean this).
'ghastly'+'new'='ghastlynew'
'ghastlynew' anagrammed gives 'LENGTHWAYS'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for lengthways that I've seen before include "In a direction along an object" , "In the direction of the longest dimension" , "going from end to end" .)
