# alphalist = ['']
# alphalist.each do |item|
#   puts 'type words one at a time and I will alphabetize them for you.'
#   alphalist.push gets.chomp

you run gets here  ^^^^

#   if gets == ''

and here ^^^

that will execute gets twice
the gets == '' will never be true so the ff line is never run

#     puts alphalist.sort
#   end
# end
# 
# ... it prints a gets value twice, then starts again with "type words
# one at a time and I will alphabetize them for you."
# If i hit enter it just puts a blank line.


how about trying something simple

alphalist = []
loop do
  puts 'type words one at a time and I will sort them for you.'
  input = gets.strip
  exit if input.empty?
  puts "-----o-----"
  puts alphalist.push(input).sort
end
