Creativity of gifted travellers in one country (11)
I believe the answer is:
imagination
'creativity' is the definition.
(I know that imagination is a type of creativity)
'gifted travellers in one country' is the wordplay.
'gifted travellers in' becomes 'imag' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'one' becomes 'i' (Roman numeral).
'country' becomes 'nation' (synonyms).
'imag'+'i'+'nation'='IMAGINATION'
'of' is the link.
Can you help me to learn more?
(Other definitions for imagination that I've seen before include "Power of creative thought" , "Mental creativity" , "Creative mental power" , "Power of mental invention" , "Mental ability to be creative" .)
