仔

suffix: diminutive suffix (small, young, or endearing), child; son
仔

Wiktionary's 仔 entry documents this diminutive/child sense chiefly for Cantonese, Hakka, and Northern Min, cross-referencing 囝 for the corresponding Teochew reading, so the precise sense boundary for gian2 is inferred rather than directly labeled Teochew on the page.
