From the Latin root gradus/gradi, meaning to step, walk, or move.
To regress is to travel back
as is to retrogress, you know.
To egress is to leave a lack
of you, as you do outward go.
Moving toward was once aggression
since the Latin “ag” means “to”;
but agress’s new suggestion
is a violent thing to do.
That which moves into ingresses
so it’s an ingredient;
that which moves ahead progresses
but there’s no “progredient.”
Digressions move apart (from what
is usually unspecified);
Transgressions move across (to cut
across a boundary is implied).
To congress is to move with others
though our congress rarely does;
most’s votes are canceled by another’s:
the “with”, I fear, just never was.
