sulky pose

Issa　一茶1815　ａｇｅ ５２

妹が子やくねた形りでよぶ忖
imo ga ko ya jikuneta nari de yobu hotaru

David’s English

my child strikes
a sulky pose
calling fireflies

The phrase, imo ga ko ("sister's child") means, in literary usage, "my wife's child," ergo, "my child." (Shinji Ogawa). Issa was newly married when he wrote this poem but still without children. Perhaps he is looking ahead with optimism, imagining that the child in the scene is his own.
