Questions & Answers about Me importa que ellos hayan encontrado la combinación.
Why do we use hayan encontrado instead of the normal past tense encontraron?
The phrase me importa que (it matters to me that) expresses an emotion or a personal evaluation, which triggers the subjunctive mood. Since the action of finding the combination already happened, we need the present perfect subjunctive, which is formed by combining the subjunctive form of the helper verb haber (hayan) with the past participle encontrado.
Why is importa in the singular "it" form if the sentence mentions "they" (ellos)?
Could I change the word order and say hayan ellos encontrado?
No, in Spanish you can never separate the helper verb (hayan) and the past participle (encontrado). They are two halves of the same verb tense and must stay glued together. Any subject pronouns like ellos must go before or after the entire two-word verb phrase.
