On the same page, I stay calm, ultimately (6)
I believe the answer is:
ibidem
'on the same page' is the definition.
I can't tell whether this definition defines the answer.
'i stay calm ultimately' is the wordplay.
'stay' becomes 'bide' (synonyms).
'ultimately' suggests the final letters.
The final letter of 'calm' is 'm'.
'i'+'bide'+'m'='IBIDEM'
Can you help me to learn more?
(Other definitions for ibidem that I've seen before include "In the same place, used in referencing" , "In the same source (Latin)" , "In the same place (Latin)" , "In the same book or passage, often abbreviated" , "Abbreviation meaning in same book or passage" .)
