In which we may see pride in the end go before a fall? (3-4)

'in which we may see pride' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'the end go before a fall?' is the wordplay.
'end' suggests the final letters.
'before' is a charade indicator (letters next to each other).
'a fall?' becomes 'trip' (as in tripping over).
The last letter of 'the' is 'e'.
'e'+'go'+'trip'='EGO-TRIP'

'in' acts as a link.

Can you help me to learn more?
