View Loch Ness catching also head of serpent (9)
I believe the answer is:
landscape
'view' is the definition.
(thesaurus)
'loch ness catching also head of serpent' is the wordplay.
'loch' becomes 'l'.
'ness' becomes 'cape' ('cape' can be a synonym of 'ness').
'catching' indicates putting letters inside.
'also' becomes 'and' (I've seen this before).
'head of' suggests taking the first letters.
The initial letter of 'serpent' is 's'.
'l'+'cape'='lcape'
'and'+'s'='ands'
'lcape' going around 'ands' is 'LANDSCAPE'.
(Other definitions for landscape that I've seen before include "Oil perhaps" , "improve grounds" , "scene" , "Painters may paint it" , "Countryside painting" .)
