Trespass originally every day, in other words indefinitely (4,3)
I believe the answer is:
sine die
'indefinitely' is the definition.
(I've seen this before)
'trespass originally every day in other words' is the wordplay.
'trespass' becomes 'sin' (I've seen this in another clue).
'originally' says to take the initial letters.
'in other words' becomes 'ie' (abbreviation for 'id est', 'that is' in Latin).
The initial letters of 'every day' is 'ed'.
'sin'+'ed'+'ie'='SINE DIE'
(Other definitions for sine die that I've seen before include "With no appointed date for resumption (Latin)" , "Indefinitely (Latin, as applied to sporting suspensions)" , "undated" , "For an indefinite period (Latin)" , "indefinitely adjourned" .)
