obstructionist

the word "obstructionist" is built upon the latin verb struere, "to build," which itself has deep roots in proto-indo-european stereu-, "to spread, extend, pile up." the prefix ob-, meaning "against," reverses the constructive action, creating the core concept of "building against" or "blocking up." this formed the latin obstruere, "to block, build against." the english noun "obstruction" emerged from this, naming the act of blocking. finally, the agent suffix -ist was appended, a productive suffix from greek -istes via latin and french, to designate a person who habitually engages in the act of obstruction, particularly in political contexts.

Structure: ob (against) + struct (to build) + ionist (one who practices) - ob: a latin prefix meaning "against, in the way of, toward". - struct: from latin struere, meaning "to pile up, build, assemble". - ionist: a combination of the noun-forming suffix -ion (indicating an action or process) and the agent-noun suffix -ist (meaning "one who practices or is concerned with").
