Each of these words can be split in half, and two letters can be placed in the middle to create a new six-letter word.
The four added pairs of letters, in order, spell an 8-letter word. What is that word?
LEND
LIAR
PALE
COIN
As an example, DOOR can be split into DO + OR. CT can then be placed in the middle to create: DO + CT + OR = DOCTOR.
