Etymology
The word "restrain" entered English in the 14th century from Old French restreindre, which itself descended from Latin restringere, meaning "to bind back, tie fast, check." The Latin verb is a compound of the prefix re- (meaning "back") and stringere (meaning "to draw tight, bind"). The core logic is vividly physical: to pull something back and hold it tight. Over time, this literal sense of physical binding evolved to encompass more abstract forms of control, such as holding back emotions, actions, or forces. Thus, the modern meaning retains the essential idea of applying a force (the "strain") to pull something back ("re-") from a course it might otherwise take.
Analysis
Structure: re (again, back) + strain (to bind, tighten)
re: Latin origin, a prefix meaning "again" or "back."
strain: From Latin stringere (to bind, draw tight), via Old French estreindre. It functions as the core root conveying the sense of binding or applying pressure.
