Altweibersommer

Etymology
At least in the meaning "Indian summer", seemingly from, literally "old women's summer". Compare 🇨🇬, 🇨🇬, archaic 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬, and 🇨🇬; compare also ; the Polish and Czech terms for the season are also used for the webs. DWDS suggests the use for cobwebs could be comparing them to old women's white hair, like the name of the wood anemone,, and a regional name for cottongrass,. Alternatively, the middle element may be a regional variant of  (cognate to 🇨🇬), or related to  (meaning, and related to, ).

Compare 🇨🇬, traditionally taken to be from "goose summer" and to have originally referred to the season (like 🇨🇬) and then to webs; DWDS considers the connection of that word with summer and this word with uncertain, but besides other summery words for the webs like  (cognate to 🇨🇬),, and , there are words like.
