When giving directions, say only the names of the streets in the order they’ll be encountered with two exceptions: For left turns prefix the name of the street with “l'” the way the French use a definite article before words that start with a vowel. For anything more complex than a simple right or left turn, just explain it. For example, walking directions to my house from Porter Square: Head Northeast on White, l’Elm for just a sec, Hancock, l’Charnwood, Willow, l’Hawthorne.
