Usage Note
Sea is the third-person singular (and first-person singular) present subjunctive of ser. It appears constantly in set phrases: o sea ('that is to say', 'I mean'), sea como sea ('be that as it may'), and ya sea...ya sea ('whether...or'). Because subjunctive mood is required after doubt, emotion, and subordinating conjunctions in Spanish, sea is among the most frequent subjunctive forms learners encounter.
Examples
"Quiero que sea verdad."
Natural Translation

I-want that it-be true.
