The following co‎des have been written using Python.

opp_dict = dict()

while True:

   key = input("Enter a word/Type 'end' to finish: ")

   if key == 'end' or key == 'End':

       break

   else:

       value = input("Enter its opposite: ")

       opp_dict[key] = value

   print()

print()

rev_opp_dict = dict()

s = 0

lk = list(opp_dict.keys())

lv = list(opp_dict.values())

while s < len(lk):

   rev_opp_dict[lv[s]] = lk[s]

   s = s + 1

w = input("Enter a word: ")

if w in opp_dict.keys():

   print("The opposite of", "'" + w + "'", "is", "'" + opp_dict[w] + "'.")

elif w in rev_opp_dict.keys():

   print("The opposite of", "'" + w + "'", "is", "'" + rev_opp_dict[w] + "'.")

else:

   print("Oops! We don't know the opposite of", "'" + w + "'.")
