انفست

Uncertain:

• A suggested root from Middle Iranian *ham-fasta (“shaken together”) from *fand- (“to shake”). Compare with Classical Persian آفند (āfand, “attack; fight”).
• Another suggested root from Middle Iranian *ham-basta (“bound together”) from an estern Iranian language. Compare with Persian انبست (anbast, “coagulated”, literally “tied together”) from [Book Pahlavi needed] (hmbst' /⁠hambast⁠/).
• Another suggestion from Middle Iranian *hamwast; ultimately from Proto-Indo-European *weh₂t- (“possessed”).

   • 10th c., Khusrawi, [Untitled work], quoted in Dehkhoda Dictionary:

     عنکبوت بلاش بر دل من
     گرد گرد بر تنید انفست

     ankabūt-i balā-š bar dil-i man
     gird gird bar tanīd anfast

     The spider of their mischievousness, in my heart
     Tangled much spiderwebs
