Speechify like a top US reformer? (5)
I believe the answer is:
spout
'speechify' is the definition.
(thesaurus)
'top us reformer?' is the wordplay.
'reformer?' is an anagram indicator (letters are re-formed in a new order).
'top'+'us'='topus'
'topus' with letters rearranged gives 'SPOUT'.
'like a' acts as a link.
(Other definitions for spout that I've seen before include "Talk at length; part of kettle" , "rant" , "Pouts beneath jet of liquid" , "Make speech; part of teapot" , "Projecting tube through which liquid is poured" .)
