Starts to keep up right vessel of people in the Taurus Mountains (7)
I believe the answer is:
kurdish
'of people in the taurus mountains' is the definition.
The definition suggests a singular noun which matches the answer.
'starts to keep up right vessel' is the wordplay.
'starts to' suggests taking the first letters.
'vessel' becomes 'dish' ().
The first letters of 'keep up right' is 'kur'.
'kur'+'dish'='KURDISH'
Can you help me to learn more?
(Other definitions for kurdish that I've seen before include "Iranian language spoken also in Turkey, Iraq and Syria" , "Of a Middle Eastern people" , "Middle-Eastern language" , "Foreign tongue" .)
