Morphology

constrain = strain (semi-transparent) = con + strain

The form 'con' + 'strain' is historically and formally transparent, but the shift to the meaning 'force/restrict' is not fully obvious to an average B1 learner from 'strain' alone.

Etymology

Constrain comes from Latin parts con- meaning 'together' and stringere meaning 'to bind' or 'to draw tight', and it shares this idea with the everyday word string. So to constrain someone is like 'tying' or 'tightening' them, which explains why it means to limit or force someone by reducing their options.
