If JACKET is coded as 146542 and COAT is coded as 6942, then what word does the code 6965 represent in the same code language?

By mapping the individual letters to their respective digits from both given words:
From JACKET $\to$ J=1, A=4, C=6, K=5, E=4, T=2
From COAT $\to$ C=6, O=9, A=4, T=2

We need to decode 6965:
6 $\to$ C
9 $\to$ O
6 $\to$ C
5 $\to$ K
So, the word is COCK.
