Not a dumb question, at all, because the terms are in most cases functionally
synonymous, so confusing.

R and R1 and R1b are all clades because they're groups defined cladistically.
Every clade, except the "root" clade, is a subclade of something else. So...
R1b is clade that is a subclade of R1; R1 is a clade that is a subclade of R;
and R is a clade that is a subclade of P; and so on.
