'i learn it off by heart essentially with other things' is the definition.
I can't judge whether this defines the answer.

'i learn it off by heart essentially' is the wordplay.

'by' means one lot of letters go next to another.
'essentially' indicates the central letters.
The centre of 'heart' is 'a'.
'learn'+'it'='learnit'
'learnit' is an anagram of 'nterali'.
'i'+'nterali'+'a'='INTER ALIA'
