Each infinitive is associated with the same information as the canonical forms and also the following attributes are added: conjugation model, number of conjugated forms, type of irregularity and/or defectiveness if it has one. The grammatical categories considered for the verbs are: transitive, intransitive and pronominal. Infinitives with different grammatical categories are stored in different entries in order to correctly establish derivative, semantic, synonymic, etc. relationships. Also, the conjugation model is a factor that influences when storing the same infinitives with a different conjugation model since it affects the conjugate forms associated with each one. This classification has led, for example, to the following entries in the Lexicon TIP:
Engrosar: Two transitive, two intransitive and two pronominal. This duplicity is due to the fact that this verb admits a regular and an irregular conjugation in all its grammatical categories. All entries have the corresponding attributes and conjugations.
Despelotar: Two transitive and four pronominal. This verb has four different etymologies. A different entry is stored for each grammatical category of each etymology. All entries have the corresponding attributes and conjugations.
Under this criterion the TIP Lexicon consists of:
|Unique infinitives||14 616|
And the distribution by grammatical categories is:
Each infinitive has stored all the conjugated forms that correspond to it, regardless of its frequency of use in Spanish. All the irregular bends have associated the type of irregularity that has (orthographic, accentuation, morphological, other) and its frequency in the CREA.
