Key Rules & Conventions
The Primary Letter Rule
Always compare the first letter of each word first.
This is the initial step for all alphabetical sorting. Group or order all words based on their first letter before proceeding to any other comparison.
The Second Letter Tie-Breaker Rule
If the first letters are identical, use the second letter to determine the order.
When you have a group of words that all start with the same letter, their relative order is decided by the alphabetical position of their second letter. If the second letters are also a tie, you would proceed to the third, and so on.

B.sorting tie on the Primary Sort Key ('T') is resolved by the Secondary Sort Key ('h'), leading to another tie.
C.The Primary Sort Key ('T') and Secondary Sort Key ('h') are identical, so the order is determined by the third letters, 'e' and 'e', which is another tie, and then the fourth letters, 'm' and 's'. 'm' comes before 's', so 'Theme' is first.
