In burial site, weep and part (5)

Ross

I believe the answer is:

crypt

I'm a little stuck... Click here to teach me more about this clue!

'in burial site' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'weep and part' is the wordplay.
'weep' becomes 'cry' (synonyms).
'and' is a charade indicator (letters next to each other).
'part' becomes 'pt' (abbreviation).
'cry'+'pt'='CRYPT'

Can you help me to learn more?

(Other definitions for crypt that I've seen before include "Undeground room" , "Underground room of church" , "Sepulchre" , "Burial vault" , "Underground burial chamber" .)
