A snitch in crossword puzzles is most commonly clued by short synonyms like RAT (3 letters), FINK (4), or TELL (4), with INFORMER (8) and STOOLPIGEON (11) appearing for longer slots. If you share the exact letter pattern and length from your puzzle, I can pinpoint the most likely answer. If you’re stuck, here are quick strategies:

• For 3-letter slots: RAT is the classic fit.
• For 4-letter slots: FINK or TELL are the common options; RAT is too short for these slots, so check the crossing letters.
• For 5–8 letters: TATTLER (7), TATTLETALE (10), or INFORMER (8) are frequent choices; look at crossing letters to decide.
• For very long slots (9–11): STOOLPIGEON (11) or TATTLETALE (10) appear in many grids.

Would you like to share the clue’s length and any known crossing letters? Then the most probable answer can be determined precisely.
