Female bears worn-out in ceremonies at the end? (4,5)

I believe the answer is:
last rites
'ceremonies at the end?' is the definition.
I can't judge whether this defines the answer.
'female bears worn-out' is the wordplay.
'female' becomes 'lass' (lass is a kind of female).
'bears' is an insertion indicator (some letters carry or bear others).
'worn-out' becomes 'trite' (I've seen this in another clue).
'lass' going around 'trite' is 'LAST RITES'.
'in' is the link.
Can you help me to learn more?
(Other definitions for last rites that I've seen before include "religious ceremony" , "Starlet is having final sacraments before death" , "final service, maybe" , "Those near death may be given these" , "Leaving ceremony" .)
