In the same place I wait on the first of May (6)
I believe the answer is:
ibidem
'in the same place' is the definition.
(synonyms)
'i wait on the first of may' is the wordplay.
'wait' becomes 'bide' (I've seen this in another clue).
'on' says to put letters next to each other.
'the first of may' becomes 'm' (1st letter of 'may').
'i'+'bide'+'m'='IBIDEM'
(Other definitions for ibidem that I've seen before include "Abbreviation meaning in same book or passage" , "In the same place as previously mentioned" , "Notation meaning in same book or passage, often shortened" , "Previously cited (in this book)" , "In the same source (Lat.)" .)
