Proposed Definition
Prenex predicate abstraction. x1 is such that the contained bridi holds true of it. Contains a {ke'a} whose antecedent is the x1 of the poi'i-abstraction. Allows for many kinds of argument-fronting and mid-sentence prenexes.

Examples
poi'i is a NU abstractor, therefore a poi'i-phrase has the form poi'i [bridi] (kei), and behaves as a selbri. Thus it has a syntax different from that of poi. It's a kind of syntactic sugar, it helps having more word order freedom. The ke'a within the bridi enclosed by poi'i...kei binds to (stands for) the x1 of the selbri created by poi'i...kei. poi'i parallels the English construction X is such that ... it ...
fo'a poi'i (ke'a) broda (kei) = fo'a is such that [ it/him/he/they ] is broda = fo'a broda |
la .pam. cu melbi gi'e poi'i so'i da nelci = la .pam. cu melbi gi'e se nelci so'i da Pam is beautiful and is such that many like her. = Pam is beautiful and is liked by many. |
Here, poi'i so'i da nelci ke'a, underlined in the example, is a predicate which means x1 is such that many things like x1.

Mid-sentence prenex:
la .pam. cu melbi gi'e poi'i so'i da nelci ke'a Pam is beautiful and is liked by many. ...is such that many like her [literally] |
Mid-sentence prenex with nested pronoun:
la. pit. cu stati gi'e poi'i so'i da manci lo nu ke'a dansu Pete is talented and many are amazed by his dancing. |

Merits
poi'i has a wide range of applications, from fluid prenexes to jai-like argument fronting (but without needing fai) and is helpful when a bridi contains complex scope interactions. It allows one to easily express complex reflexives, and overall increases Lojban's flexibilty at the word order level. As poi'i is like a mid-sentence prenex, it also enables the use of quasi-prenexes after bridi-tail connectives (see examples above).
