Mountain guide in new phase touring capital of Romania (6)
I believe the answer is:
sherpa
'mountain guide' is the definition.
(I've seen this before)
'new phase touring capital of romania' is the wordplay.
'new' indicates anagramming the letters.
'touring' indicates putting letters inside (touring can mean going round).
'capital of' suggests taking the first letters.
The first letter of 'romania' is 'r'.
'phase' is an anagram of 'shepa'.
'shepa' placed around 'r' is 'SHERPA'.
'in' acts as a link.
(Other definitions for sherpa that I've seen before include "- - Tensing" , "Skilled Himalayan mountaineer" , "Skilled mountaineer of the Himalayas" , "Highly competent guide" , "Himalayan - phrase (anag)" .)
