Start with "STAIN":

stain

"S" is in the solution but in a different spot. "T", "A", "I", and "N" are not in the solution.

$ grep -P '(?=^[^stain][^tain]{4}$)(?=.*s.*)(?!.*[[:punct:]].*)' /usr/share/dict/words

Guess with "YOURS":

Start with "STAIN".

stain

The letters "S", "T", "A", and "N" are not in the final word. "I" is in the correct position.

Use the following regular expression:

$ grep -P '^[^stan][^stan][^stan]i[^stan]$' /usr/share/dict/words
