'given a coat' is the definition.
The definition and answer can be both to do with creating things as well as being past participle verbs.
Maybe there's an association between them I don't understand?

'english celebrity escorted across lake' is the wordplay.
'english' becomes 'E' (abbreviation).
'celebrity' becomes 'name' (as in a 'big name').
'escorted' becomes 'led' (to lead someone somewhere is to escort them).
'across' is an insertion indicator.
'lake' becomes 'L' (geographical abbreviation).
'led' going around 'l' is 'lled'.
'e'+'name'+'lled'='ENAMELLED'
