There is no adequate English word that will substitute. Scripture describes Jesus as a paraclete, and Jesus tells his disciples that he will send his spirit to them so they will not be alone. People everywhere these days are looking for ways to have an encounter with God. Angels are big everywhere. I hear descriptions of people being rescued by angels.
People say they have conversation with their angels.
It is angels that guide decisions in their lives, people say. But sometimes I wonder if all this business about angels isn't just more baggage. When we listen carefully to the description of the Holy Spirit, it seems like we are giving credit to angels for what God is doing directly in our lives. The Holy Spirit is the mysterious power of God in the lives of God's people. The Holy Spirit is the personal presence of God in our lives.
