A bare infinitive is an infinitive (that is, the non-finite base form of a verb) that is used without the infinitive marker to: I would rather stay at home. A non-finite clause that is headed by a bare infinitive is called a bare infinitive clause: They made me do it. (AEG Ch. 2, Ch. 4)

Beneficiary
Beneficiary is a semantic role; it refers to the one for whose benefit something is done. In an activesentence, a constituent having the semantic role of beneficiary regularly functions as IO and takes the form of an NP (William baked me a cake) or a for-PrepP (William baked a cake for me). Beneficiaries are not very common in a passive sentences; when they occur, they function as Subject: I was baked a cake. (AEG Ch. 2)
