Which term is used to describe a dirty, mean, or poverty-stricken appearance?

The term "squalid" is used to describe a dirty, mean, or poverty-stricken appearance, effectively conveying a sense of filth, neglect, or extreme poverty. This word originates from the Latin "squalidus," which means "filthy" or "dirty." When describing a living condition or environment as squalid, it implies a lack of cleanliness and care, often highlighting unhygienic situations that result from poverty or neglect.

In contrast, "shrewd" refers to having sharp judgment or being astute, particularly in practical matters. "Reverence" denotes deep respect or admiration, which has no connection to physical appearance. "Shard" refers to a piece or fragment of something, typically broken glass or pottery, and does not relate to any context of appearance or condition. Thus, squalid stands out as the accurate descriptor for a dirty or impoverished state.
