Is there a official logical fallacy that covers equating two or more alternative meanings or connotations of the same word in an argument to reach a faulty conclusion?
Examples:
Animals aren’t allowed in the hosptial
Humans are animals, (not plants)
Therefore humans are not allowed in the hospital
Criminals should be locked up for the good of society.
Entering the country without documentation is a crime
Therefore people who enter the country without documentation should be locked up for the good of society.
12-year-old Roger, 10-year-old Floyd, and 7-year-old Dale are brothers. Of Roger’s 2 brothers, Floyd is the older one. Of Dale’s 2 brothers, Floyd is the younger one. So, Floyd is his older brother’s older brother. Floyd is also his younger brother’s younger brother.
