Appearance made by em-cee performing without right info (9)
I believe the answer is:
emergence
'appearance' is the definition.
(I know that emergence is a type of appearance)
'em-cee performing without right info' is the wordplay.
'performing' is an anagram indicator (the letters move around or 'perform').
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'right' becomes 'r' (common abbreviation).
'info' becomes 'gen' (informal term for information).
'cee' anagrammed gives 'ece'.
'r'+'gen'='rgen'
'ece' going around 'rgen' is 'ergence'.
'em'+'ergence'='EMERGENCE'
'made by' is the link.
(Other definitions for emergence that I've seen before include "Development" , "First appearance" , "A coming forth" , "Advent" , "Sudden appearance" .)
