Idioms idioms – non-composition meaning i.e. meaning of idiom cannot be inferred from the meaning of the constitutive words examples – John kicked the bucket VP “kicked the bucket” – has a literal interpretation – has an idiomatic interpretation “John died” – Pete gave me the cold shoulder VP “give X the cold shoulder” – has an (unlikely) literal interpretation – has a (more likely) idiomatic interpretation “be unfriendly towards X” – (French) cassé sa pipe – (literal) break his pipe – (idiomatic) died

Idioms examples – John kicked the bucket VP “kicked the bucket” – has a literal interpretation – has an idiomatic interpretation “John died” – John kicked the buckets VP “kicked the buckets” – has only a literal interpretation English grammar modifications: – verb: kicked – common noun: bucket(s) queries ?- parse(X,[john,kicked,the,bucket]). X = kicked(john,bucket) ?- parse(X,[john,kicked,the,buckets]). X = kicked(john,buckets) – Literal meanings only

Idioms examples – John kicked the bucket VP “kicked the bucket” – has a literal interpretation – has an idiomatic interpretation “John died” – John kicked the buckets VP “kicked the buckets” – has only a literal interpretation idiomatic interpretation – Verb Phrase: kicked the bucket – vp(vp(v(died))) --> [kicked,the,bucket]. Modify Predicate-Argument structure (intransitive verbs)

Idioms example – John kicked the bucket VP “kicked the bucket” – has a literal interpretation – has an idiomatic interpretation “John died” – John kicked the buckets VP “kicked the buckets” – has only a literal interpretation queries – ?- parse(X,[john,kicked,the,bucket]). – X = died(john) ? ; – X = kicked(john,bucket) ? ; – ?- parse(X,[john,kicked,the,buckets]). – X = kicked(john,buckets) ? ; – no

Exercise: English Idiom example – John kicked the bucket the VP “kicked the bucket” has a literal interpretation and an idiomatic interpretation “John died” vp(vp(v(died))) --> [kicked,the,bucket]. Complete the translator so that – John kicked the bucket has both a literal and an idiomatic translation Taroo-ga buketsu-o ketta Taroo-ga shinda buketsu = bucket shinda = died ketta = kicked – John kicked the buckets has only a literal translation Taroo-ga buketsu-o ketta (assuming Japanese does not distinguish number)
