Root Breakdown
Root-derivedcon- (thoroughly, together) + strain (bind, draw tight) = to bind tightly on all sides. To be constrained is to be roped in until your options are squeezed down — hence both "limit" (constrain growth) and the stronger "compel" (constrained to obey): when every other path is bound off, only one is left.

- Limit sense (common, often passive): budgets are constrained, growth is constrained by resources.
- Compel sense (formal/literary): be constrained to do something = forced by circumstances to do it.
Most everyday use is the limit sense; the "compel" sense sounds formal.
