Unclogging is the process of removing blockages or obstructions from something. Synonyms for unclogs include dislodges, clears, frees, unblocks, and opens up. These words imply removing something that is stopping the flow of movement or activity. For example, a plumber would unclog a drain by dislodging debris or clearing a blockage. A teacher might unclog a student's understanding by explaining a concept in a different way. A person might unclog their congested nose by using a nasal spray. In all these cases, the goal is to achieve an unimpeded state where things can flow more freely.
