Morphology
friction = frict + ion
The form contains the combining form 'frict' plus the nominalizing suffix '-ion'; 'frict' is not a standalone English base, so learners cannot derive the meaning from familiar English components.
Etymology
The word friction comes from the Latin fricare, meaning 'to rub', and the noun frictio for 'rubbing'. So friction is the resistance you feel when two surfaces rub against each other.
