(last noun) ’y) (word (bl noun) ’ies) (word noun ’s))) > (every plural ’(beatle turtle holly kink zombie)) ;; example input (beatles turtles hollies kinks zombies) ;; expected output instead receive error "variable every not bound". if 'every' being treated variable rather known function. receive same error when try examples 'keep' , 'accumulate'. coding correct assume (since copied book i'm reading). wrong in thinking these functions built in , not need defined or there other issue? hope can shed light on this. the...
