With "SACRAMENTARIANS" as the guessed word:

• the 'S' in the final position matches the S in both potential solutions, thus the 'G' in the final spot
• 2 A's in the guessed word but wrong position, thus 'Y', but the last 'A' is extra, so '-'
• 1 of the R's in the guessed word matches the occurance in the potential solution but wrong position. The other 'R' is extra
• same for T
• 'E' and 'I' should be straightforward.
