Plural of 'chirology'; multiple studies, systems, or branches of hand study or analysis.
From 'chirology' with the regular plural ending '-ies' (used when nouns end in a consonant + 'y'). The word itself comes from Greek 'cheir' (hand) and 'logos' (study).
The plural 'chirologies' is interesting because it suggests there could be many different hand-study systems—and indeed, from palmistry to forensic fingerprinting to orthopedic therapy, there really are multiple ways of studying hands, each with its own approach.
