Hamper and impede both slow progress without stopping it, with different pictures of the slowing. To hamper is to encumber — something clings, clogs, or weighs so the work drags: searches hampered by fog, reform hampered by red tape. To impede is to obstruct the way forward — from Latin 'to shackle the feet': obstacles in the path, each step costing extra. Hampered efforts drag their burden; impeded ones climb over snags.
English keeps a small crowd of hindering verbs, and these two are the precision pair. Both leave the goal reachable — that is what separates them jointly from prevent — and both are happiest in the passive with by: hampered by, impeded by. The nuance is the mechanism. Hamper suggests encumbrance riding along: weight, clutter, friction that never lets go. Impede suggests obstruction in the road: its Latin root impedire literally means to shackle the feet (the same pes, 'foot', as pedal), and its noun impediment still names the specific thing in the way — most familiarly in 'a speech impediment'.
hamper
To hamper is to make something harder to do — to clog, drag on, or get in the way so that progress is slowed rather than stopped. Thick fog hampers a search; heavy bags hamper a traveller; red tape hampers reform. The word suggests friction and encumbrance: the effort still moves forward, but everything about it now costs more and takes longer because something keeps catching at it from the side.
impede
To impede is to slow something that is trying to move. The Latin impedire meant 'to shackle the feet' — im- on, pes foot — and the image still fits: what impedes does not destroy or forbid; it ties weights to every step. Bad weather impedes a rescue, bureaucracy impedes innovation, an injury impedes recovery. The destination usually stays reachable — impeding steals time and effort, not the goal itself, which is what separates it from 'prevent'.

The wrench and the snag-lane. Hampered is the gear train with a wrench jammed in its teeth: still turning, but grinding for every degree — the interference rides inside the works. Impeded is the runner in the snag lane: the destination never moves, but every stride costs a stagger and a hop. Both machines finish; both arrive angry. When the drag clings to the effort itself, hamper; when obstacles stud the path forward, impede — and when neither nuance matters, hinder covers the ground plainly.

The hindering family grades finely: hinder is the plain umbrella; hamper adds the clinging-burden flavour; impede adds the obstacle-course one; obstruct hardens toward blocking outright (obstructing justice is a charge, not a delay). Only impede keeps a working noun — impediment, the named thing in the way — while hamper's noun life belongs to an unrelated word, the picnic or laundry basket. Their shared opposite, facilitate, anchors the exam pairing: whatever facilitates smooths the path these verbs roughen.
Problem-solution essays run on the pair's passives — 'efforts were hampered by a lack of funding', 'bureaucracy impedes innovation' — and reading questions paraphrase both as hinder or slow down. Impediment upgrades noun phrases: 'a major impediment to trade' outclasses 'a big problem for'. Keep the joint antonym pairing ready (impede versus facilitate is a tested contrast on this site's facilitate pages), and let obstruct carry only genuine blockage.
