[Hey!]

PSST

Think of the quiet sound you might make to get someone’s attention without speaking aloud—it’s often whispered in secret.

The clue "[Hey!]" is a playful way to hint at a quiet or secretive call for attention. "PSST" is an onomatopoeic word used to get someone’s notice without being obvious, often whispered to avoid drawing attention. The exclamation mark in the clue signals that the answer is an interjection, and "PSST" fits as a hushed alternative to a loud "Hey!" It’s a classic crossword trick where the answer mimics the sound or tone of the clue.
