Tehrani regularly flying one further east? (4)
I believe the answer is:
thai
'flying one further east?' is the definition.
Although both the answer and definition are adjectives, I cannot understand how they can define each other.
'tehrani regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternate letters of 'tehrani' are 'THAI'.
Can you help me to learn more?
(Other definitions for thai that I've seen before include "Eg, native of Bangkok" , "One from Bangkok" , "Asian language" , "From Bangkok, for instance" , "Native of Southeast Asia" .)
