The Language reference set is essential to enable the preferred terms to be identified for each concept. Language reference sets refers to Descriptions that is used in a particular language or dialect. For each Description referenced in the language reference set a value for the acceptability of the term associated with that Description is assigned. The values for the Acceptability attribute is represented by descendants of the concept

Available values for acceptability |
| Value | Description |

| 900000000000548007 | Preferred (foundation metadata concept) | | The term associated with this description is the preferred description, of the specified Description.typeId, for the associated concept, in the language or dialect represented by this reference set.
If the Description.typeId is synonym, this description is the preferred term.
If the Description.typeId is fully specified name this description is the preferred fully specified name.
For each concept there should be exactly one preferred description of each Description.typeId in each language reference set. |

The following diagram shows an example of the description file included in the International Release and the US Language reference set, which is also distributed with the International Release of SNOMED CT. The language reference set states the acceptability of the descriptions, i.e. whether they are preferred or synonym. For each concept there may be any number of acceptable descriptions of each description type in each language reference set. The diagram below shows how the description file holds information about the description type, and the language reference set specify the acceptability of the descriptions.

descriptionId, and the description release file is therefore a prerequisite for retrieving the actual term when applying the
language reference set .
