Act it out without a word (5)
I believe the answer is:
tacit
'without a word' is the definition.
I can't judge whether this definition defines the answer.
'act it out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'act'+'it'='actit'
'actit' with letters rearranged gives 'TACIT'.
Can you help me to learn more?
(Other definitions for tacit that I've seen before include "Understood without being directly expressed" , "without speaking" , "Understood, implicit" , "Implied, unstated" , "Understood, not spoken or played" .)
