Left still on the loch (5)

I believe the answer is:

leven

'loch' is the definition.
(I've seen this before)

'left still on' is the wordplay.
'left' becomes 'l' (common abbreviation).
'still' becomes 'even' (synonyms).
'on' says to put letters next to each other.
'l'+'even'='LEVEN'

'the' is the link.

(Another definition for leven that I've seen is " Loch".)

I've seen this clue in the Evening Standard.
