Small Dotless J Modifier with Stroke and Hook

It marks a secondary or lightly articulated ʄ-like sound.

Here ʄ is the full-size IPA letter for a voiced palatal implosive: a consonant made with vocal-fold vibration and inward airflow near the hard palate, or roof of the mouth. The superscript can mark a ʄ-like release, a sound colored by ʄ, or a weak, fleeting, or inserted ʄ-like element. It modifies a main sound instead of naming a full consonant on its own.

The written history of its form predates Unicode. A related J-shaped sign with a hook at the top for a palatal implosive appears in 1963; references from 1971 and 1984 record the closer form: a dotless j crossed by a stroke and with a hook at the top.

Why is 𐞘 separate from ʄ?

Because superscript status changes the transcription.

In phonetic writing, superscript placement can mark secondary or incomplete articulation. The dedicated character keeps its modifier status in the text if styling is stripped; making the full-size ʄ look superscript may lose that distinction.

𐞘 belongs to specialist phonetic transcription, where its position signals how a sound relates to the main one.
