Dictionary Word Arrangement Explained

Arranging words in alphabetical order, like in an English dictionary, involves comparing them letter by letter from the beginning. If the initial letters are the same, we move to the next letter until a difference is found. The word with the letter that comes earlier in the alphabet is placed first.

Words for Alphabetical Ordering

Here are the words we need to arrange in dictionary order:

• 1. INTRUSION
• 2. INTRODUCE
• 3. INTRODUCTORY
• 4. INTROVERT
• 5. INTRODUCTION

Step-by-Step Dictionary Sorting Process

Let's compare the words systematically:

Comparing Initial Letters

All the given words start with the prefix "INTR". We need to look at the 5th letter to start differentiation:

Since 'O' comes before 'U' in the alphabet, words 2, 3, 4, and 5 will be placed before word 1.

Current Order Grouping: {Words 2, 3, 4, 5}, {Word 1}

Ordering based on 5th Letter

Now, let's focus on arranging the words with 'O' as the 5th letter (words 2, 3, 4, 5). We examine the 6th letter:

'D' comes before 'V'. Therefore, words 2, 3, and 5 will come before word 4.

Current Order Grouping: {Words 2, 3, 5}, {Word 4}, {Word 1}

Ordering based on 6th Letter

Next, we arrange the words starting with "INTROD" (words 2, 3, 5). We compare the 7th letter:

All these words have 'U' as the 7th letter. We continue to the next letter.

Ordering based on 7th Letter

All words have the prefix "INTRODU". We check the 8th letter:

All have 'C' as the 8th letter. Proceeding to the next letter.

Ordering based on 8th Letter

All words share the prefix "INTRODUC". Let's compare the 9th letter:

'E' comes before 'T' alphabetically. Thus, INTRODUCE (2) is the first among these three words.

Current Order: 2, {Words 3, 5}, {Word 4}, {Word 1}

Ordering based on 9th Letter

We now order INTRODUCTORY (3) and INTRODUCTION (5), which both start with "INTRODUCT". We compare the 10th letter:

'I' comes before 'O'. Therefore, INTRODUCTION (5) comes before INTRODUCTORY (3).

Order for this group: 5, 3.

Final Dictionary Order Result

Combining all the comparisons, the complete alphabetical order of the words is:

1. INTRODUCE (2)
2. INTRODUCTION (5)
3. INTRODUCTORY (3)
4. INTROVERT (4)
5. INTRUSION (1)

The correct sequence representing this order is 2, 5, 3, 4, 1.
