At the urging of KAH, I recently switched from relatively generic fish oils (Target, Meijer), to this fancy Omega 3.6.9 from Nordic Naturals. It differs from the rest of its ilk because it is “filtered” and I am letting myself believe that that is important….
Sometimes investigating jargon leads us to interesting vocabulary lessons. I recall some time ago when I encountered the word “subaltern” and had no idea what it meant. The usage was in the jargon of agency studies (and Anthony Giddens), and referred to the low status and powerlessness of the commoner masses (I think). The word, however, has an upstanding prior meaning. As a noun, it meant a low-ranking British army officer. As an adjective, it did refer to those of low status (hence its co-opting by social theorists), but it also has this meaning (thank you Apple Dictionary):
Over my head!
