Expressing 'behalf'

Prepositional phrases may be used to express 'behalf', using the preposition for or complex prepositions such as on behalf of, for the sake of, in favour of:

His former teacher put in a good word for my brother. [Who did my teacher put in a good word for?]
My brother phoned the police on behalf of my sister. [On whose behalf did my brother phone the police?]
We attended the school concert for the sake of my little sister. [For whose sake did we attend?]

Circumstance 'behalf' or Participant 'Beneficiary'

The Circumstance 'behalf' may be confused with the Participant 'Beneficiary':

She made up a story for her brother. [a story to tell her brother at bedtime]
                                    Beneficiary

This is similar to she made a sandwich for her brother, with its alternative she made her brother a sandwich. In both examples her brother is the Beneficiary, ie a Participant. However, she made up a story for her brother is ambiguous, ie the function of the prepositional phrase may be to express the Circumstance 'behalf':

She made up a story for her brother.
                                  Circumstance

[a story to tell to someone else on behalf of her brother]
