Understanding Alphabetical Order

Arranging words in alphabetical order is a fundamental skill used when searching for words in a dictionary or list. It involves comparing words letter by letter from the beginning until a difference is found. The word with the letter that comes earlier in the alphabet is placed first.

We are given the following words to arrange in alphabetical order:

1. Threaten
2. Thorough
3. Thankful
4. Throat
5. Thereafter
6. Thistle

Step-by-Step Word Arrangement

Let's compare the words letter by letter to determine their correct dictionary order.

Step 1: Comparing the first two letters

All the given words start with the letters "Th". So, we need to look at the third letter to differentiate them.

Step 2: Comparing the third letter

Let's look at the third letter of each word:

• Threaten (Thr)
• Thorough (Tho)
• Thankful (Tha)
• Throat (Thr)
• Thereafter (The)
• Thistle (Thi)

Arranging the words based on the third letter ('a', 'e', 'i', 'o', 'r'):

• 'a' comes first: Thankful (3)
• 'e' comes next: Thereafter (5)
• 'i' comes next: Thistle (6)
• 'o' comes next: Thorough (2)
• 'r' comes next: Threaten (1) and Throat (4)

Based on the third letter, the order starts as 3, 5, 6, 2. We now need to compare Threaten (1) and Throat (4), as they both have 'r' as the third letter.

Step 3: Comparing words with the same initial letters (Threaten and Throat)

Both Threaten (1) and Throat (4) start with "Thr". We look at the fourth letter:

• Threaten (Thre)
• Throat (Thro)

Comparing the fourth letters 'e' and 'o', 'e' comes before 'o' in the alphabet.

Therefore, Threaten (1) comes before Throat (4).

Final Alphabetical Order

Combining the results from the comparisons, the correct alphabetical order of the words is:

1. Thankful (3)
2. Thereafter (5)
3. Thistle (6)
4. Thorough (2)
5. Threaten (1)
6. Throat (4)

The sequence of the word numbers is 3, 5, 6, 2, 1, 4.

Thus, the correct order of the words as they would appear in an English dictionary is 3, 5, 6, 2, 1, 4.
