Signare could be likened to a type of signature that, when you were skilled enough, could help you identify what practitioner that cast a specific spell[1], or in any case Nightingale claims to be able to do so.[2] Since both of them were trained by the same master (Nightingale), Peter Grant could sense the similarities in Lesley May's signare and his own.[3]

A practitioner can't mask their signare.[4]

The signare of the Faceless Man is a razor strop.[5]
