Excited Jordanian ran away to border (6)
I believe the answer is:
adjoin
'border' is the definition.
(synonyms)
'excited jordanian ran away' is the wordplay.
'excited' indicates anagramming the letters.
'away' suggests deleting specific letters.
'jordanian' with 'ran' taken away is 'jodian'.
'jodian' anagrammed gives 'ADJOIN'.
'to' is the link.
(Other definitions for adjoin that I've seen before include "Of building, be situated next to" , "Be next to, say building" , "Be next or nearest to" , "Abut, border" , "Be next to, like building" .)
