-ER/-IR Verbs Ending in Vowel in Spanish Past Perfect Subjunctive

-ER/-IR verbs ending in vowel in the Spanish Past Perfect Subjunctive typically add a ‘y’ before the -ido ending when forming the past participle. This change prevents the formation of a diphthong and maintains proper pronunciation.

For example, ‘creer’ (to believe) becomes ‘creído’, and ‘oír’ (to hear) becomes ‘oído’. When used with the Imperfect Subjunctive of ‘haber’, these form expressions like ‘hubiera/hubiese creído’ (I would have believed) or ‘hubieran/hubiesen oído’ (they would have heard).
