I'm a little stuck... Click here to teach me more about this clue!

'greets' is the definition.
(hailing is a kind of greeting)

(Other definitions for hails that I've seen before include "Greets" , "Attracts attention by calling to someone" , "pelts" , "Praises" .)

I've seen this clue in the Evening Standard.
