| == Natural Language ==
| |
| In the UNL<sup>arium</sup> framework, conjunctions are classified as follows
| |
| *'''coordinating conjunctions (COO)''' join two or more items of equal syntactic importance ("and", "or", "but");
| |
| **'''correlative conjunctions (CRC)''' are pairs of conjunctions that work together to coordinate two items (both … and, (n)either … (n)or, not (only) … but (also)....);
| |
| *'''subordinating conjunctions (SCJ)''' introduce a dependent clause. They are further classified in:
| |
| **'''Complementizers (CMR)''' are special subordinating conjunctions that introduce complement clauses ("that" in "I know that he came");
| |
| **'''Adverbializers (AVR)''' are special subordinating conjunctions that introduce adverbial clauses ("after" in "I go after you go");
| |
| **'''Relativizers (RVZ)''' are special subordinating conjunctions that introduce relative clauses.
| |

| | |
| == UNL ==
| |
| In UNL, conjunctions are explicitly represented by attributes, except in case of complementizers ("if", "that", "whether") or when their semantic value may be inferred from the corresponding relation.
