Understanding Dictionary Order Arrangement

Arranging words in dictionary order, also known as alphabetical order, involves comparing words letter by letter starting from the first letter. If the first letters are the same, we compare the second letters, and so on, until a difference is found. The word with the letter that comes earlier in the alphabet is placed first.

Step-by-Step Word Arrangement Process

Let's take the given words and arrange them according to the dictionary rules:

1. Engine
2. Emergence
3. Energetic
4. Ectasia
5. Envelope

We will compare the words based on their numbering:

• Word 1: Engine
• Word 2: Emergence
• Word 3: Energetic
• Word 4: Ectasia
• Word 5: Envelope

Now, let's compare the words letter by letter:

1. Comparing the first letter: All words start with 'E'. So, we move to the second letter.
2. Comparing the second letter:
   • Engine: 'n'
   • Emergence: 'm'
   • Energetic: 'n'
   • Ectasia: 'c'
   • Envelope: 'n'
   The letters are 'n', 'm', 'n', 'c', 'n'. In alphabetical order, 'c' comes first, followed by 'm', and then 'n'. So, 'Ectasia' (4) comes first, followed by 'Emergence' (2).
3. Comparing the words starting with 'En': We have Engine (1), Energetic (3), and Envelope (5). Let's compare their third letters:
   • Engine: 'g'
   • Energetic: 'e'
   • Envelope: 'v'
   The letters are 'g', 'e', 'v'. In alphabetical order, 'e' comes first, followed by 'g', and then 'v'. So, 'Energetic' (3) comes before 'Engine' (1), which comes before 'Envelope' (5).

Combining the results from the comparisons, the correct dictionary order is:

1. Ectasia (4)
2. Emergence (2)
3. Energetic (3)
4. Engine (1)
5. Envelope (5)

The sequence of the numbers corresponding to this order is 4, 2, 3, 1, 5.

Final Dictionary Order Sequence

Based on the step-by-step comparison, the words arranged in dictionary order are: Ectasia, Emergence, Energetic, Engine, Envelope. The corresponding sequence of their original numbers is 4, 2, 3, 1, 5.

Additional Information: Alphabetical Sorting Tips

When performing alphabetical sorting for dictionary arrangement, keep the following in mind:

• Always start comparing from the very first letter of each word.
• If the letters at the current position are identical for two or more words, move to the next letter position in those words.
• Continue this process until a position is reached where the letters are different. The word with the letter appearing earlier in the standard English alphabet (A-Z) comes first.
• If one word runs out of letters while being compared to a longer word that matches it so far, the shorter word comes first (e.g., 'cat' comes before 'cattle').
• Ignore capitalization unless specified otherwise (standard dictionary order is case-insensitive).
