quickener
That which hastens
Something that quickens—that is, something that accelerates, enlivens, or stimulates.
A quickener of the pulse raises the heart rate; a quickener of interest sparks engagement.
The word appears in religious contexts for that which brings spiritual life: the Holy Spirit as quickener of the soul.
Rarely used outside literary or theological writing.
