Lexeme
A Lexeme is considered notable if:
 * 1) there's at least one notable Form in the Lexeme, and
 * 2) the Lexeme is idiomatic.

Note we do not exclude terms originating in fictional universes.

Idiomaticity
Whether a Lexeme is idiomatic is up to community. However, these type of Lexemes are allowed in principle:
 * 1) Any Lexeme in  with a sense which is a single word.
 * 2) Any number between 0 and 100, inclusive; by contrast, numbers, numerals, and ordinals over 100 that are not single words or are sequences of digits are not considered idiomatic per se.
 * 3) Phrasebook entries (very common expressions that are considered useful to non-native speakers).

Sometimes, a phrase may be included by the consensus of the community, based on the determination of editors that inclusion of the term is likely to be useful to readers.

Proper nouns
Proper nouns should be included if they meet one of the following conditions:
 * 1) There are multiple senses (multiple Gratisdata items with this label)
 * 2) They are etymologically important (some common noun or other part of speech is derived from this proper noun, e.g. adjective)
 * 3) They have been included in multiple authoritative dictionaries or similar sources
 * 4) They are a part of another proper noun (for example given or family names)
 * 5) They have inflections

Proper nouns already added that do not meet one of these criteria may be retained, but they should not be systematically added outside of these conditions.

Phonemes
Phonemes are not accepted as lexemes. They have to be stored as items.

Graphemes
Graphemes are not accepted as lexemes. They have to be stored as items.

Form
A Form is considered notable if:
 * 1) it is or can be attested, or
 * 2) it is a inflection form or term in alternative script or orthography, but attestation is needed if the existence of such Form is likely to be disputed.

Attestation
"Attested" means verified through:
 * 1) use or mention in at least one serious source; or
 * 2) two other sources, provided that they can be archived somewhere (e.g. at archive.org), and are in different sentences by different people, and are spanning at least six month.

Sources should be provided through, entries in dictionaries with , or thorugh providing dedicated properties with external identifiers. Quotes may be added with the qualifier.

Note this does include nonce words and dictionary-only terms.

Sense
A Sense is considered notable if it is or can be attested.

Languages
Any language is included as long as they are notable as Gratisdata item. This broadly includes:
 * 1) All natural languages.
 * 2) Sign languages.
 * 3) Constructed languages like Esperanto and Toki Pona, and artistic languages like Klingon.
 * 4) Reconstructed languages such as Proto-Indo-European.

Note community may explicitly include or exclude a language based on consensus, such as when a proposed language is considered a dialect of or alternate name for another language.
