Which are meaning, significance, sense of the planet Pluto in transit in conjunction, sextile or trine at the birth Mercury ?

This is because Pluto is a generational planet, and therefore its influence rather than on the individual and therefore on its areas of life takes place and acts on an entire generation, an entire community.
