Adult who's lost east of American city, carelessly (6)

Ross

I believe the answer is:

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

'adult who's lost east of american city' is the wordplay.
'adult' becomes 'a' (abbreviation).
'lost' is an anagram indicator.
'east of' is a charade indicator (letters next to each other).
'american city' becomes 'ny' (I've seen this in other clues).
'who' with letters rearranged gives 'how'.
'how' put after 'ny' is 'nyhow'.
'a'+'nyhow'='ANYHOW'

(Other definitions for anyhow that I've seen before include "Whatever's happened", "Carelessly", "Not in an orderly manner, by whatever means", "in a mess", "Randomly - at least".)

I've seen this clue in The Independent.
