pabulum

Borrowed from Latin pābulum (“food, nourishment; fodder or pasture for animals; nourishment for the mind, food for thought”), from pā(scō) (“to nourish”) + -bulum (suffix denoting an instrument), or directly from Proto-Indo-European peh₂-dʰlom (peh₂- (“to protect, shepherd”) + -dʰlom, variant of -trom (suffix denoting a tool or instrument)).
