Understanding Alphabetical Order of Words

This question asks us to arrange a list of English words in the sequence they would appear in a standard English dictionary. This process involves comparing words letter by letter from the beginning to determine their correct alphabetical placement.

List of Given Words

The words provided for ordering are:

1. 1. SPINY
2. 2. SPINE
3. 3. SPINACH
4. 4. SPINNEY
5. 5. SPIRIT
6. 6. SPIKE

Step-by-Step Word Ordering Process

To achieve the correct dictionary order, we compare the words based on their letters sequentially from left to right.

1. Comparing the First Three Letters: All the given words begin with the same three letters: 'SPI'. This means we need to look further into the words to determine their order.

2. Comparing the Fourth Letter: We now examine the fourth letter of each word to establish the primary sorting groups:

• SPIKE (6) - The fourth letter is 'K'.
• SPINACH (3) - The fourth letter is 'N'.
• SPINE (2) - The fourth letter is 'N'.
• SPINNEY (4) - The fourth letter is 'N'.
• SPINY (1) - The fourth letter is 'N'.
• SPIRIT (5) - The fourth letter is 'R'.

According to the English alphabet, 'K' comes before 'N', and 'N' comes before 'R'. This establishes the following order for the main groups: words starting with 'SPIK', followed by words starting with 'SPIN', and finally words starting with 'SPIR'.

• Based on this, SPIKE (word 6) comes first.
• The group of words starting with 'SPIN' (words 1, 2, 3, 4) will follow SPIKE.
• SPIRIT (word 5) comes last due to its fourth letter 'R'.

This gives us a partial order: 6, {1, 2, 3, 4}, 5.

3. Ordering the 'SPIN' Words: Next, we must arrange the four words that start with 'SPIN' – SPINACH (3), SPINE (2), SPINNEY (4), and SPINY (1) – into their correct alphabetical sequence. We do this by comparing their fifth letters:

• SPINACH (3) - The fifth letter is 'A'.
• SPINE (2) - The fifth letter is 'E'.
• SPINNEY (4) - The fifth letter is 'N'.
• SPINY (1) - The fifth letter is 'Y'.

The alphabetical order of these fifth letters (A, E, N, Y) dictates the order within this subgroup:

• SPINACH (3)
• SPINE (2)
• SPINNEY (4)
• SPINY (1)

This sequence corresponds to the number order: 3, 2, 4, 1.

4. Determining the Final Correct Order: By combining the order of the main groups ('SPIK', 'SPIN', 'SPIR') with the internal order of the 'SPIN' words, we get the complete alphabetical sequence.

The final determined order is:

SPIKE (6), followed by SPINACH (3), SPINE (2), SPINNEY (4), SPINY (1), and finally SPIRIT (5).

Therefore, the correct sequence of numbers representing the alphabetical order is 6, 3, 2, 4, 1, 5.

Note: The derived order based on standard dictionary rules is 6, 3, 2, 4, 1, 5. This differs from the sequence presented in option 3 (3, 6, 2, 4, 1, 5). The explanation provided adheres to the standard methodology for alphabetical sorting.
