What does obstructionist mean?
An obstructionist is someone who deliberately prevents progress or a decision, particularly by using delays, procedural rules, or repeated objections. The word is especially common in political and legislative reporting, where an obstructionist may seek to block a bill, inquiry, reform, or other measure without directly opposing it. As an adjective, obstructionist describes tactics or conduct intended to create delay or resistance. The term normally carries a strongly critical connotation: it suggests purposeful obstruction rather than ordinary disagreement, caution, or criticism. Because it implies deliberate obstruction, it is best reserved for situations in which someone is persistently hindering an agreed process or decision. The related adjective obstructive is more general and can describe any person, thing, or action that presents a hindrance.
A person who deliberately impedes progress, discussion, or decision-making, especially through procedural delays or institutional tactics.
"A few determined obstructionists managed to postpone the hearing for another week."
Most often used in political, legislative, and institutional contexts, with a critical connotation.
Relating to or intended to obstruct progress, decision-making, or the operation of a process.
"Lawmakers rejected the proposal as an obstructionist measure rather than a genuine reform."
Usually placed before a noun such as tactics, strategy, approach, or measure.
The plural refers to people who deliberately impede progress or use procedural tactics to block action.
"The organization was criticized for encouraging obstructionists to filibuster the amendment."
An obstructionist's most effective weapon may be procedure itself: delay can block a decision without requiring a direct vote against it.

Where does obstructionist come from?
