Left east with one garland (3)
I believe the answer is:
lei
'garland' is the definition.
(I know that garland can be written as lei)
'left east with one' is the wordplay.
'left' becomes 'l' (common abbreviation).
'east' becomes 'e' (synonyms).
'with' is a charade indicator (letters next to each other).
'one' becomes 'I' (Roman numeral).
'l'+'e'+'i'='LEI'
(Other definitions for lei that I've seen before include "Polynesian garland of flowers" , "What Romanians spend" , "Bloomers on line" , "Hawaiian garland - Romanian money" , "Hawaiian ring of flowers" .)
