KK: /ɪˌlɑːdʒɪˈkælɪti/
A state or condition of being unreasonable or not making sense.
The illogicality of his argument made it hard to take him seriously.
Illogicality → It is formed from "il-" (meaning not), "logic" (from Greek "logikē", meaning reasoning or thought), and "-ity" (meaning the state or quality of). The word describes the state of being not logical or lacking reason.
Think of 'not' ('il-') combined with 'reasoning' ('logic') to remember that 'illogicality' means the quality of being unreasonable.
