Noun
: a person who owns a building with apartments that are in bad condition and rents them to poor people.
I came this word in the reading excerpt, “The Boston Photographs” . When I saw at the sentence ” …the Boston pictures sowed the dangers of fire escapes and raised questions about slumlords.” I guess this word may mean places or person, after I looked at the dictionary. Definitely my guess is right, now I have an idea of this word means.
