Can be used both literally (physical obstruction) and metaphorically (hindering progress or actions).
Use '阻挡' when describing physical or metaphorical blocking actions. For more formal or deliberate obstruction, '阻止' might be more appropriate.
In technical or formal contexts, '阻挡' can imply a more passive or structural obstruction, while '阻止' suggests active prevention.
Combination of '阻' (to obstruct) and '挡' (to block), both characters reinforce the idea of preventing movement or progress.
Often used in both physical and metaphorical contexts. In formal contexts, it can imply a deliberate act of obstruction.
