Arranging Words in English Dictionary Order

To arrange words in the order they appear in an English dictionary, we compare them letter by letter from left to right. We look at the first letter of each word. If they are the same, we move to the second letter, and so on, until we find a difference. The word with the letter that comes earlier in the alphabet will be placed first.

Let's apply this process to the given words:

1. PREREQUISITE
2. PRESCRIPTION
3. PREPOSITION
4. PREROGATIVE
5. PREPOSTEROUS

Step-by-Step Comparison for Dictionary Order

All the words start with the prefix "PRE". Let's look at the fourth letter of each word:

• PREREQUISITE: R
• PRESCRIPTION: S
• PREPOSITION: P
• PREROGATIVE: R
• PREPOSTEROUS: P

The fourth letters are R, S, P, R, P. Arranging these letters alphabetically (P, P, R, R, S), we group the words accordingly:

• Words with 'P' as the 4th letter: PREPOSITION (3), PREPOSTEROUS (5)
• Words with 'R' as the 4th letter: PREREQUISITE (1), PREROGATIVE (4)
• Words with 'S' as the 4th letter: PRESCRIPTION (2)

Comparing Words within Groups

Group 1: Words starting with "PREP"

We compare PREPOSITION (3) and PREPOSTEROUS (5):

• PREPOSITION
• PREPOSTEROUS

Both words start with "PREPO". Let's look at the sixth letter:

• PREPOSITION
• PREPOSTEROUS

Comparing 'I' and 'O', 'I' comes before 'O' in the alphabet. Therefore, PREPOSITION comes before PREPOSTEROUS.

Order for this group: 3, 5

Group 2: Words starting with "PRER"

We compare PREREQUISITE (1) and PREROGATIVE (4):

• PREREQUISITE
• PREROGATIVE

Both words start with "PRER". Let's look at the fifth letter:

• PREREQUISITE
• PREROGATIVE

Comparing 'E' and 'O', 'E' comes before 'O' in the alphabet. Therefore, PREREQUISITE comes before PREROGATIVE.

Order for this group: 1, 4

Group 3: Word starting with "PRES"

PRESCRIPTION (2) is the only word in this group. It will come after the "PREP" and "PRER" groups because 'S' comes after 'P' and 'R'.

Order for this group: 2

Final Dictionary Order Arrangement

Combining the groups in the order of their 4th letters (P, R, S):

1. Group starting with PREP: PREPOSITION (3), PREPOSTEROUS (5)
2. Group starting with PRER: PREREQUISITE (1), PREROGATIVE (4)
3. Group starting with PRES: PRESCRIPTION (2)

The final order of the words is 3, 5, 1, 4, 2.
