Reveal short guy lived in different places (7)
I believe the answer is:
divulge
'reveal' is the definition.
(I know that reveal can be written as divulge)
'short guy lived in different places' is the wordplay.
'short' means to remove the last letter.
'in different places' indicates an anagram (I've seen this in other clues).
'guy' with its last letter removed is 'gu'.
'gu'+'lived'='gulived'
'gulived' anagrammed gives 'DIVULGE'.
(Other definitions for divulge that I've seen before include "Make (secrets) known" , "Reveal as with information" , "Make public" , "Make known (a secret)" , "Disclose (a secret)" .)
