Roughly beneath tip of elephant's trunk (5)
I believe the answer is:
torso
'trunk' is the definition.
(synonyms)
'roughly beneath tip of elephant's' is the wordplay.
'roughly' becomes 'orso' (synonyms).
'beneath' says to put letters next to each other (in a down clue).
'tip of' suggests the final letters.
The final letter of 'elephant' is 't'.
'orso' put after 't' is 'TORSO'.
(Other definitions for torso that I've seen before include "Roost (anag)" , "Trunk, something unfinished" , "Limbless statue" , "Body's trunk" , "Body, minus its head and limbs" .)
