Single Minded Riley

Question

My first crack at a 'Riley Riddle':

My Prefix is full of class
My Infix is deceased
My Suffix is unorthodox
My Whole is one-sided

Answer 1

You are:

UNILATERAL

My Prefix is full of class

As an educational establishment, UNI (University) is full of class (i.e. lectures, etc.).

My Infix is deceased

LATE is a synonym for 'deceased' (e.g. 'the late Mr so-and-so'...).

My Suffix is unorthodox

LATERAL thinking (e.g. to crack a riddle) is not the way one would usually think, hence unorthodox...

My Whole is one-sided

Altogether, this makes UNILATERAL, which means quite literally, 'one-sided'.
