砂利

Listed in one source as possibly a shift from the sazare portion of 細石 (sazareishi, “gravel, pebble”, literally “small + stone”).[1]

• /sazare/ → */zare/ → /zari/ → /d͡ʑari/

However, the first attestation of the zari form is not until 1677, while the jari form is first cited to 1619.[2]

The child sense originates as a jargon term at places such as a theatre, initially in reference to child visitors.[3][4][5][2]

• (Tokyo) じゃり [jàrí] (Heiban – [0])[1][3][6]
• IPA^(key): [d͡ʑa̠ɾʲi]

砂(じゃ)利(り) • (jari) 

1. [from 1619] gravel
2. [from 1804] a magistrate's office for adjudicating issues from commoners (from the rock gardens that were common at these during the Edo period)

   Synonym: 白洲 (shirasu)

3. [from 1844] child

• 切込(きりこ)み砂利(じゃり) (kirikomi jari)
• 砂利(じゃり)タレ (jari tare)
• 砂利場(じゃりば) (jari ba)
• 玉砂利(たまじゃり) (tama jari)
• 山砂利(やまじゃり) (yama jari)

Appears to be a shift from the jari reading.
