Crossword Genius

Name given to salt lake (4)

Ross

I believe the answer is:

tarn

'lake' is the definition.
(tarn is a kind of lake)

'name given to salt' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'given to' means one lot of letters go next to another.
'salt' becomes 'tar' ('tar' can be a synonym of 'salt').
'n' after 'tar' is 'TARN'.

(Other definitions for tarn that I've seen before include "Small mountain lake" , "High water" , "Scottish mountain lake" , "Mountain pool: French department" .)

I've seen this clue in The Telegraph.
