Why I get terribly heavy (7)

Ross

I believe the answer is:

weighty

'heavy' is the definition.
(synonyms)

'why i get terribly' is the wordplay.
'terribly' is an anagram indicator.
'why'+'i'+'get'='whyiget'
'whyiget' is an anagram of 'WEIGHTY'.

(Other definitions for weighty that I've seen before include "Cumbersome" , "having great influence" , "significant" , "Important" , "Heavy - very serious" .)

I've seen this clue in the Evening Standard.
