Arranging Words in Dictionary Order

To arrange words in dictionary order, we compare them letter by letter from left to right. The word that comes first alphabetically based on the first differing letter is placed earlier in the sequence.

Step-by-Step Word Comparison

We are given five words with their corresponding numbers:

Let's compare the words character by character:

• All words start with 'In'.
• Compare the third letter:
  • Words 1 and 2 start with 'Inf'.
  • Words 3, 4, and 5 start with 'Ind'.
• Since 'd' comes before 'f' in the alphabet, words starting with 'Ind' will come before words starting with 'Inf'.

Arranging the 'Ind' Words (3, 4, 5)

Let's compare Indirect (5), Indulge (3), and Induce (4):

• All start with 'Ind'.
• Compare the fourth letter:
  • Indirect (5): 'i'
  • Indulge (3): 'u'
  • Induce (4): 'u'
• 'i' comes before 'u', so Indirect (5) is the first word in this group.
• Now compare Indulge (3) and Induce (4). Both start with 'Indu'.
• Compare the fifth letter:
  • Indulge (3): 'l'
  • Induce (4): 'c'
• 'c' comes before 'l', so Induce (4) comes before Indulge (3).

The order for the 'Ind' words is: 5 (Indirect), 4 (Induce), 3 (Indulge).

Arranging the 'Inf' Words (1, 2)

Let's compare Infect (1) and Inferior (2):

• Both start with 'Inf'.
• Compare the fourth letter:
  • Infect (1): 'e'
  • Inferior (2): 'e'
• Both start with 'Infe'.
• Compare the fifth letter:
  • Infect (1): 'c'
  • Inferior (2): 'r'
• 'c' comes before 'r', so Infect (1) comes before Inferior (2).

The order for the 'Inf' words is: 1 (Infect), 2 (Inferior).

Final Dictionary Order

Combining the two groups, with 'Ind' words coming before 'Inf' words, the final dictionary order is:

1. Indirect (5)
2. Induce (4)
3. Indulge (3)
4. Infect (1)
5. Inferior (2)

The sequence of the original numbers is 5, 4, 3, 1, 2.

Additional Information: Alphabetical Sorting

Alphabetical sorting, or arranging words in dictionary order, is a fundamental skill. It is used extensively in dictionaries, encyclopedias, indexes, and lists of names. When sorting, if two words have the same letters up to a certain point, the word with the letter that comes earlier in the alphabet at the next position is placed first. If one word is a prefix of another (e.g., 'cat' and 'catalog'), the shorter word typically comes first.
