Manteniéndolas
Manteniéndolas is the Spanish gerund form of mantener when combined with a feminine plural direct object pronoun. It expresses an ongoing action of keeping, maintaining, or preserving something that is feminine and plural, previously referenced in the discourse. The base verb mantener means to maintain, keep, or support, and the gerund manteniendo conveys the progressive aspect. When a pronoun such as las is attached to the end of the gerund, the form becomes manteniéndolas. The accent on the í is required to preserve the correct stress after adding the pronoun.
Usage is typical in constructions with auxiliary verbs to form progressive phrases, especially with estar: La
Notes on scope and references: This form is common for referring to items such as las instalaciones,
