The letters of TALES have been added to the grid to form six words, one being a lingual import into English.

L	E	A	S	T
S	L	A	T	E
S	T	A	L	E
S	T	E	A	L
T	A	E	L	S
T	A	L	E	S

Assign a base 10 digit to each of the letters in the grid to create an alphametic so that each row but one forms a 5-digit prime number.

This situation can occur in three ways, and logic should prevail.

The "three ways"?

Well,  I did derive 3 in my spreadsheet.  I did attempt to cycle the respective valid digits from the lowest 5-digit number to the highest.  Very clearly I omitted some combination swaps.

Putting the values you have for LEAST into my spreadsheet confirms that my spreadsheet is correct but I was not diligent enough with my swapping of values.
