Act it differently, not using words (5)
I believe the answer is:
tacit
'not using words' is the definition.
I can't tell whether this definition defines the answer.
'act it differently' is the wordplay.
'differently' is an anagram indicator.
'act'+'it'='actit'
'actit' anagrammed gives 'TACIT'.
Can you help me to learn more?
(Other definitions for tacit that I've seen before include "Aircraft engine casing" , "Unspoken but implied" , "Silent but implied" , "Implied without being said" , "Implied but not directly expressed" .)
