Irregular verbs

For all the irregular verbs, the morphological changes that affect the conjugated forms of the verb are detailed in the Additional Information section. Each change is explained in a different morphological Note. The changes considered are those that affect both the structure of the root, as well as the ending or the accentuation of a conjugated form (see, for example, the verbs ir, ser, tener,...).

For all those regular or irregular verbs, where the conjugation has been affected by orthographic changes resulting from compliance with the spelling rules of Spanish, the orthographic changes that affect the conjugated forms of the verb are detailed in the Additional Information section. Each change is explained in a different Spell Note. The changes considered are those related to the changes of the g for gu, g for j, c for qu and c for z, and vice versa in all cases (see, for example, the verbs seguir, menguar, dirigir, delinquir, ejercer, aparcar, ligar, adelgazar, ...). In addition, pressing with the mouse on any Spelling Note you access the list of verbs that fit the indicated in the note.

Both the Morphological Notes and the Spelling Notes can be individually selected so that, when you click on the button Highlight the irregular forms, the conjugated forms that meet the selected notes are highlighted in color. This allows the reader to easily identify the irregular forms of a verb and those that have been affected by a spelling change. In addition, pressing with the mouse on any morphological Note accesses the list of verbs that conform to what is indicated in the note.

The academic orthography of 1999 introduced changes in the graphic accentuation of some monosyllables directly affecting the conjugation of some verbs (criar, fiar, freír, etc.). For that reason and not to confuse the reader, Conjugador TIP keeps the two versions clearly indicated with a Spelling Note.

Morphological irregularities

This section shows a calisification of irregular verbs based on the morphological changes involved in the conjugation of their forms. The New Grammar of the Spanish Language does not include certain aspects considered here as morphological changes but of another nature, for example phonological. This article only aims to help the reader to better understand the conjugation of Spanish by showing groupings of verbs that meet a specific irregularity or change with respect to the regular conjugation paradigms.

Verbs that modify their accentuation with respect to the regular conjugation

Verbs that change letters in some forms with respect to the regular conjugation

Verbs that add irregularly shaped letters in some forms

Verbs that lose irregularly shaped letters in some forms

Defective verbs

Defective verbs are those verbs that don't have complete conjugation sets. Some verbs are only defective as empedernir or atardecer and others who are depending on their meaning with which they are used, for example, poner or estar (see these verbs in the dictionary of the Royal Spanish Academy). Defective types in verbs are listed (terminology used is that of Institute of Hispanic Verbology):

Conjugador TIP shows a message with the type of defectiveness that the conjugated verb has and it is possible, by pressing the mouse button on the message, to access the list of verbs that have the same defectivity. We have found discrepancies about the defectivity of some verbs in the consulted sources, a feature that we have clearly highlighted with a message.


Irregular participles

The New Grammar of the Spanish Language calls the irregular participles also strong participles because they present the accent in the root and tend to be inherited forms of Latin. Just as the irregularities of the conjugation have been studied by linguists, the same does not occur with the irregularities of the particles. Simply, the irregular participles come from Latin and you have to learn them as such. The classification that is shown for the irregular participles is made from an objective point of view and without entering to evaluate the linguistic considerations that could exist associated to each one. As in the rest of the articles, the idea is to help memorize and use better the conjugation of Spanish verbs from the study of groups of verbs that have a certain characteristic.

Orthographic variants

The New Grammar of the Spanish Language does not consider morphological irregularities the orthographic variants that obey certain systematic rules of application in the Spanish language. The classification presented groups the verbs that change their conjugation for orthographic reasons. Some of the verbs included in these groups are considered by some of the sources consulted as regular when they do not have another type of additional irregularity in their conjugation. These groupings can help to better understand the application of the orthographic rules of Spanish and, specifically, its application to the conjugation of verbs.
