What is the difference between liquor and liqueur we here you ask?
Generally speaking liqueurs are sweeter however with flavoured liquors available this can be confusing! Liquors are typically your base drink whilst liqueurs you add to flavour your drink (although some can be drunk alone)
Liquor is what we know commonly as 'spirits', an alcoholic beverage made up of grains or other plants that are fermented such as your typical Whiskeys, Brandy, Gin, Rum, Tequila and Vodka. These liquors are often used as a base for cocktails or as a mixer such as rum and coke or gin and tonic. They can also be drunk neat as 'shots'.
Liqueurs are sweetened spirits with various flavours, oils and extracts added and in the past were often called 'cordials'. Amp up your cocktails with a well chosen liqueur!
