IPA: /ˌoʊliˈmɑːrdʒərɪn/
KK: /oʊliˈmɑrʤərɪn/
A type of spread made from vegetable oils and water, often used as a substitute for butter.
Many people use oleomargarine instead of butter for cooking and baking.
Oleomargarine → It is formed from "oleo-" (from Latin "oleum", meaning oil) and "margarine" (from Greek "margaritēs", meaning pearl). The word refers to a substance that resembles butter and is made from oil, hence the combination of oil and the idea of a pearl-like appearance.
Think of 'oil' ('oleo-') and something that looks like a 'pearl' ('margarine') to remember that oleomargarine is a butter substitute made from oil.
