Por ejemplo, hay un conjunto de verbos irregulares que se conjugan, para sus dos formas del tiempo pasado, con la terminación ‘-ought’. Estos son ‘to think’ (pensar), ‘to buy’ (comprar), ‘to bring’ (traer), ‘to fight’ (pelear), ‘to seek’ (buscar).
Dos casos particulares de los verbos irregulares son los verbos que cumplen simultáneamente la función de concepto de acción y de auxilar: el verbo ‘have’ (que en las dos conjugaciones del pasado es ‘had’) y el verbo ‘is/are’ (que en past simple será ‘was/were’ y en past participle ‘been’) son los mejores ejemplos de eso.
Si en el tiempo continuado presente los verbos se conjugan con ‘is/are + verbo con ‘ing’, en el pasado contínuo la conjugación será en cambio ‘was/were + verbo con ‘ing’. Asimismo, si el present perfect se conjuga con ‘have + participle’, entonces el past perfect se conjugara con ‘had + participle’. En ese contexto es que eventualmente podrá existir la duplicación ‘had had’.
