The biblical words for "Spirit" derive from words meaning blow, breath, wind, and the like. This etymology does not mean that the Holy Spirit is God's breath or a force that emanates from God.
Bad Arguments against the Personhood of the Holy Spirit
Why the parallelism between the Holy Spirit and the power of God in Luke 1:35 does not prove that the Holy Spirit is God's power rather than a divine person.

Some opponents of the Trinity argue that the Holy Spirit is not a person because the noun pneuma is neuter, or because neuter pronouns are used in reference to the Spirit. This article explains why these are bad arguments.
