Like 600 in uniform breaching shatter'd Crimean line (9)
I believe the answer is:
numerical
'like' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'600 in uniform breaching shatter'd crimean line' is the wordplay.
I cannot quite understand how this works, but
'uniform' could be 'u' (phonetic alphabet: alpha, bravo, charlie etc.) and 'u' is present in the answer.
an anagram of 'crimean' is 'nmerica' which is within the remaining letters.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for numerical that I've seen before include "Relating to such as 9 or 123" , "expressed in figures" , "Relating to quantity" , "Muriel can (anag)" , "of digits" .)
