To form a regular conditional tense verb, you need to start with the infinitive of the verb, for example 'terminar' or 'ir'Remember that the endings for conjugation are the same as for ir/er verbs in the imperfect tense. (ía, ías, ía, íamos, íais, ían)Add these endings to the infinitive, eg 'Terminaría' = I would finish, or irían= They would goThere are also some irregulars which need to be learnt as they do not follow this pattern, for example 'hacer' becomes 'haría' (I would do).
