To give it significance, at the end we land outside (4,6)

'to give it significance at' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'end we land outside' is the wordplay.
'land' becomes 'light' (lighting is a kind of landing).
'outside' indicates putting letters inside.
'end'+'we'='endwe'
'endwe' put inside 'light' is 'LEND WEIGHT'.

'the' acts as a link.

Can you help me to learn more?
