Dictionary Word Order Explained

To determine the correct dictionary order for the words universe, unicorn, understood, unhappy, and uniform, we compare them letter by letter.

Step-by-Step Word Sorting

1. Compare First Letter: All words begin with 'u'.
2. Compare Second Letter: All words have 'n' as the second letter (un-).
3. Compare Third Letter:
   • understood -> 'd'
   • unhappy -> 'h'
   • unicorn -> 'i'
   • uniform -> 'i'
   • universe -> 'i'
   Based on the third letter, 'd' comes first, so understood (3) is the first word. 'h' comes next, placing unhappy (4) second. The remaining words all have 'i' as the third letter.
4. Compare Fourth Letter (for 'uni-' words):
   • unicorn -> 'c'
   • uniform -> 'f'
   • universe -> 'v'
   Comparing 'c', 'f', and 'v', the alphabetical order is 'c', 'f', 'v'. This places unicorn (2) next, followed by uniform (5), and finally universe (1).

Final Dictionary Order

Combining the steps, the correct dictionary order is:

• understood (3)
• unhappy (4)
• unicorn (2)
• uniform (5)
• universe (1)

This corresponds to the sequence 3, 4, 2, 5, 1.
