She's said to be slimmer (4)
I believe the answer is:
lena
'she's' is the definition.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Another definition for lena that I've seen is " River of Siberia (4400 km), the world's ninth longest".)
I've seen this clue in the Evening Standard.
Want a hint initially instead of a full solution?
