ratiocinate
Deduce through logic
To ratiocinate is to reason methodically, working through a problem step by step using formal logic.
The word is rare and deliberately highbrow—choosing it over "reason" or "think through" signals either philosophical precision or pretension: Holmes ratiocinated his way to the killer's identity.
The noun is ratiocination.
