block a path, opening, or view
to block a road, door, or view so that people, things, or light cannot go through easily
用法パターン：
to obstruct [something]
よくある間違い：
Learners sometimes say *"The tree stops the road"* instead of *"The tree obstructs the road"* or *"blocks the road"*. Also, learners may try to use *obstruct* for emotional disturbance (e.g., *"The noise obstructs me"*), where *disturb* or *bother* would be more natural.

make progress or action difficult
to make it hard for a plan, change, or activity to move forward or be successful
用法パターン：
to obstruct [activity or process]
よくある間違い：
Learners sometimes use *stop* instead of *obstruct* in formal writing (e.g., *"stop progress"*). While understandable, *obstruct* or *hinder* sound more natural in formal or written contexts. Another mistake is using *obstruct* with a person as a direct object to mean 'disagree with' or 'criticize'; *obstruct* should target the activity or process, not simply the person.
類義語
hinder (Very close in meaning; common in both formal and neutral styles for slowing progress.)
|
impede (Formal; often used in written English about processes, development, or movement of ideas or things.)
対義語
facilitate (Formal; means to make a process or action easier or more likely to succeed.)
|
promote (Means to actively support or help something to grow or succeed, the opposite of holding it back.)

interfere with legal or official process
to try to stop or change the work of the police, courts, or other officials in a way that is against the law
用法パターン：

|
tamper with (Often used when someone secretly changes or damages something involved in an investigation or process.)
