Use "orientate" in a sentence
"Some decades ago, Eric Partridge noted in Usage and Abusage that orientate is correct as an intransitive (“to face in a particular direction”), but that orient is preferable in all other senses."
"In most cases, though, this slight differentiation seems likely to be increasingly eroded, if the development of orient and orientate is anything to go by."
"Orient (v) and orientate (v) are all but interchangeable."
