Sierra Grande, ground which could produce vegetables? (7)
I believe the answer is:
gardens
'could produce vegetables?' is the definition.
I can't tell whether this defines the answer.
'sierra grande ground' is the wordplay.
'sierra' becomes 'S' (phonetic alphabet: alpha, bravo, charlie etc.).
'ground' indicates an anagram ('grind' the letters into a new form).
's'+'grande'='sgrande'
'sgrande' is an anagram of 'GARDENS'.
'which' is the link.
Can you help me to learn more?
(Other definitions for gardens that I've seen before include "Green public spaces" , "In which you find weeds" , "Park" , "Personal plots of ground" , "Cultivated grounds" .)
