Tips

register

Strictly literary/written. 盖 here is the classical particle 'because/probably' (cf. 盖闻 'one hears that…'), and 因 means 'because'. The compound 盖因 is essentially a doubled 'because' for explanatory clauses in formal essays, news editorials, or legal documents. In speech use 因为 instead — 盖因 in conversation sounds pretentious.
