Foil Characters
IntroducedA foil exists to show someone else
- Foil characters (foils) serve to illuminate, through contrast, the traits, attributes or values of another character.
- The verb is illuminate: the foil's job is to make someone else visible.
- So a foil is defined by its function, not by any quality of its own.
A foil needs no villain’s cape; their job is to make somebody else easier to see.

So a foil is defined by its function, not by a quality of its own.
Name what is illuminated
- The CED names three things a foil can illuminate: traits, attributes or values.
- X is a foil for Y identifies a pair and stops.
- X's ease with money makes Y's carefulness legible as fear rather than virtue is the analysis.

A contrast reveals nothing without the shared half- name it first

The strongest foils match on almost everything and differ on one axis.
A foil is not an opposite
- Students often look for a character who is the reverse of the protagonist in everything.
- The strongest foils differ on one axis and match on the rest — which is what makes the difference visible.
- Two characters alike in everything but one thing form a controlled comparison.

Holding everything else constant is what makes the one difference legible.
A foil is not an opposite in everything. The strongest foils match on almost everything and differ on one axis — that is what makes the difference legible. Hunting for a character who reverses the protagonist in every respect usually finds nobody, or finds the wrong person.
Foils can run both ways
- A foil illuminates the other character, and often the reverse is also true.
- When the illumination runs both ways, the pair is doing more work than a one-sided foil.
- Say which direction the text emphasises, and whether the second direction is available.

The shared list should be long — that is what makes the foil work.
A foil pass
- Name the pair, then list what they share — that list should be long.
- Name the single axis on which they differ.
- Then say what that difference makes visible about the character being illuminated.
Two cousins: same age, same schooling, same debts, same house. One asks for help once; the other never does. Everything held constant except the asking — so the novel can make a claim about pride that neither character alone would support.
Foils illuminate, through contrast, the traits, attributes or values of another character — so name what is illuminated, not just the pair. The strongest foils match on almost everything and differ on one axis, and illumination often runs both ways.
