Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating directly as 'дисперсия' (dispersion in physics/optics). Better equivalents: 'рассеивание', 'распространение', 'рассредоточение'.
- Do not confuse with 'distribution' ('распределение'), which can imply orderly arrangement, while 'dispersal' implies scattering.
Common Mistakes
- Using 'dispersal' as a verb (incorrect: 'They will dispersal the crowd'; correct: 'They will disperse the crowd').
- Confusing 'dispersal' (the event/process) with 'dispersion' (the state/measure of being dispersed).
