Crane has wing half visible, one in French river (10)
I believe the answer is:
demoiselle
'crane' is the definition.
(demoiselle is a species of crane)
'wing half visible one in french river' is the wordplay.
I cannot quite see how this works, but
'wing' could be 'ell' (ell is a kind of wing) and 'ell' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
This explanation may well be incorrect...
'has' is the link.
Can you help me to learn more?
(Another definition for demoiselle that I've seen is " Young woman (archaic)".)
