dijera
Dijera is a verb form of decir (to say or to tell) in Spanish, specifically the imperfect subjunctive. It comes from the stem derived from the preterite third-person plural decir form, dij-, with imperfect-subjunctive endings. There are two corresponding series: the ra-series, yielding forms such as dijera, dijeras, dijera, dijéramos, dijerais, dijeran; and the se-series, yielding dijese, dijeses, dijese, dijésemos, dijeseis, dijesen. Both series are correct; the ra-forms are very common, and the se-forms are used in various dialects and registers as an alternative.
Dijera is used in subordinate clauses when the main clause is in the past or in conditional
Notes on usage: the imperfect subjunctive covers a range of nuances, from hypothetical and uncertain to polite
