If my last name is Logue, should its adjectival form be Logian, Loguesque, or Loguish? The final is the only one with an English precedent (rogue, roguish), but is my least favorite; the middle is the most pleasing to my eye and preserves the nominal form within it; the first has a certain intellectual quality which I enjoy as it is analogous to most eponymous scholarly adjectives (Cartesian coordinates, Newtonian physics, Aristotelian philosophy, etc.), but it also suffers the most degradation, containing only the initial three letters of the name.
These are the important issues upon which I ponder.
