Acrobatic internet-era performer (11)
I believe the answer is:
entertainer
'performer' is the definition.
(I've seen this before)
'acrobatic internet-era' is the wordplay.
'acrobatic' indicates an anagram (letters jumping around).
'internet'+'era'='internetera'
'internetera' anagrammed gives 'ENTERTAINER'.
(Other definitions for entertainer that I've seen before include "Eg, singer or comic" , "One providing hospitality" , "One who considers" , "Arturo -, nineteeth to twentieth century Italian conductor" , "artiste" .)
