Я думаю, это то, что вы пытаетесь сделать
class Dictionary
def initialize()
@data = Hash.new { |hash, key| hash[key] = [] }
end
def [](key)
@data[key]
end
def []=(key,words)
@data[key] += [words].flatten
@data[key].uniq!
end
end
d = Dictionary.new
d['tall'] = %w(long word1 word2)
d['something'] = %w(anything foo bar)
d['more'] = 'yes'
puts d.inspect
#=> #<Dictionary:0x42d33c @data={"tall"=>["long", "word1", "word2"], "something"=>["anything", "foo", "bar"], "more"=>["yes"]}>
puts d['tall'].inspect
#=> ["long", "word1", "word2"]

Теперь избегает повторяющихся значений благодаря Array#uniq!
.
d = Dictionary.new
d['foo'] = %w(bar baz bof)
d['foo'] = %w(bar zim) # bar will not be added twice!
puts d.inspect
#<Dictionary:0x42d48c @data={"foo"=>["bar", "baz", "bof", "zim"]}>
