Current cost varied outwardly, but this person can take it (5)
I believe the answer is:
stoic
'this person can take it' is the definition.
'stoic' can be an answer for 'person' (stoic is a kind of person). I'm not certain of the rest of the definition.
'current cost varied outwardly' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'varied' indicates an anagram.
'outwardly' indicates putting letters inside (some letters go on the outside).
'cost' is an anagram of 'stoc'.
'i' inserted within 'stoc' is 'STOIC'.
'but' acts as a link.
Can you help me to learn more?
(Other definitions for stoic that I've seen before include "Long-suffering type; follower of Zeno" , "Resilient philosopher" , "Phlegmatic type" , "Philosopher like Marcus Aurelius" , "Zeno, say" .)
