How is 'party' coded in the given code language?

The common words in first two statements are 'to' and 'see' coded as = 'na' or 'di'

The common words in first and third statements are 'hope' and 'to' coded as = 'di' or 'so'

Thus, from above statements, we get : 'to' = 'di' ; 'see' = 'na' ; 'hope' = 'so'

=> Only word left in first statement is 'you' coded as = 're'

=> Only word left in third statement is 'come' coded as = 'ge'

The common word in second and last statements are 'the' and 'party' coded as = 'fi' or 'zo'

=> Only word left in second statement is 'please' coded as = 'ke'

Thus, the code for 'party' is = either 'zo' or 'fi'
