Read the FAQ explanation of Comprehensible InputReal Context
Obstruct is a transitive verb meaning to block or hinder something or someone, often by creating a barrier or impediment. It can describe physical blockage, such as a fallen tree obstructing a road, or abstract hindrance, such as red tape obstructing progress in a project. The nuance is stronger and more formal than simply block, and it frequently appears in legal or administrative contexts (obstruction of justice, obstructing an investigation). Remember the pattern: obstruct + object (obstruct the view, obstruct traffic). The prefix ob- carries a sense of opposing or facing, which helps explain why obstruction involves a barrier rather than a mere pause. Use in active voice with a clear direct object.
Usage Reminders
- Use obstruct for active hindrance with a clear object
- Prefer formal contexts (legal/administrative)
- Differentiate obstruct from block in intensity and formality
- Remember common collocates: obstruct the view, obstruct traffic, obstruction of justice
- Do not confuse with obstacle as a noun; use obstruction instead when speaking of the hindrance itself
Common Misconceptions
- Think obstruct can replace block in all contexts; it usually sounds more formal and is less common in everyday speech.
- Mistaking obstruction for obstacle; obstruction is the act or process, obstacle is the thing.
- Assuming obstruct always implies malicious intent; context matters.
- Confusing obstruct with obstructing (gerund/participle) in passive phrases.
- Neglecting to use ob- prefix meaning or misplacing the object after obstruct.
Thinking Differences
For English speakers, obstruct often carries a formal tone and is used in legal or procedural contexts; it emphasizes hindering through a barrier rather than a simple delay.
