expression, ichidan verb
spin a cocoon
Literal expression for a silkworm or caterpillar spinning its cocoon.
蚕が繭をかける時期になった。
It's the season when silkworms spin cocoons.
Alternate kanji for かける; less common but acceptable.
Compound of 繭 (mayu, 'cocoon') + を (o, object marker) + かける (kakeru, 'to hang, put on, set about'). The verb かける here carries the sense of 'to set about making' or 'to construct'.
