village
閈 centers on a village, likely as a gated or enclosed community, given its structure of a gate enclosing an inner area.
閈 combines 門 (gate) with 干, which may have contributed a phonetic element. The exact historical development is uncertain, but the structure suggests a gated place, consistent with the meaning 'village'.
Picture a village protected by a large gate 門. Inside, a shield 干 stands ready, symbolizing the community's defense. The gate and shield together represent the enclosed, safe village.
For カン, imagine a can of food being shared at the village gate: can -> カン, and the whole village gathers around it.
