GCSE Spanish Grammar: Irregular Preterite and Future Stems

Describing what happened and what will happen is essential in every part of the reformed GCSE in Spanish (first exams in 2026): the writing tasks reward past and future time frames, the role-play and the conversation ask what you did and what you are going to do, and translation tests exact forms. A small group of very common verbs is irregular in exactly these tenses, and the grammar list names them. At Foundation tier, the preterite stems tuve, pude, hice, vine, estuve, puse, quise, dije and traje, with the irregular forms of ir, ser and dar, and the future and conditional stems of tener, hacer, poder and poner, plus habrá and habría. At Higher tier, the future and conditional stems of saber, querer, venir, decir and salir are added. (This follows the Spanish grammar list in AQA's specification, for example.)

The quiz is a set of twelve gap-fill sentences. Each asks for one irregular form, with an English hint, and offers three wrong versions of the kind learners actually write: regularised stems (podí, teneré, veniré), wrong endings (pusistes), a form in the wrong tense, or a real word with another meaning (venderé, I will sell). Three questions use Higher-tier stems. The explanations give the stem and the full pattern, so each question teaches a whole verb.

The sixteen flashcards list the irregular preterite endings, each irregular preterite with its meaning, ir and ser sharing fui, dar, the regular future, the irregular future and conditional stems at both tiers, the conditional endings, and the vendré and venderé trap.

The written sheet practises the forms in use: conjugating preterites and futures, rewriting a short passage from the present into the preterite and another from the past into the future, translating into Spanish in both time frames, explaining why dijeron has no i and why irregular preterites carry no accent, and writing about your own weekend with at least four irregular verbs. Model answers are given for every item.

Learn the stems from the flashcards, drill them with the quiz, then use the written sheet to make them automatic in sentences.

• Form the irregular preterites tuve, pude, hice, vine, estuve, puse, quise, dije and traje in all persons
• Use fui for both ir and ser, and the preterite of dar
• Form the future and conditional of tener, hacer, poder and poner, and use habrá and habría
• Form the Higher-tier future and conditional stems of saber, querer, venir, decir and salir
• Avoid typical errors: regularised stems, pusistes, accents on irregular preterites
