The word “quagmire” refers to a soft, muddy area of land that is difficult to walk through. It can also be used metaphorically to describe a complex or difficult situation that is hard to escape from.
Interesting fact: The word “quagmire” originated in the 16th century and is derived from the combination of the words “quag” (meaning “bog” or “marsh”) and “mire” (meaning “mud” or “slime”).
