Citrus plant, large, moved one metre (5,4)
I believe the answer is:
lemon tree
'citrus' is the definition.
(lemon tree is a kind of citrus)
'plant large moved one metre' is the wordplay.
I cannot really see how this works, but
'plant' could be 'tree' and 'tree' is found in the answer.
'large' could be 'l' (eg in clothes sizes) and 'l' is found within the answer.
'metre' could be 'm' (synonyms) and 'm' is located in the answer.
an anagram of 'one' is 'eon' which is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for lemon tree that I've seen is " Variety of citrus".)
