Usage Note

Many verbs in English have derived from nouns. One can head an organization or toe the mark; butter the bread or bread the cutlet. Hence, grammatically at least, there is no historical justification for the once frequently heard criticism of contact used as a verb meaning “to communicate with”: The managing editor contacted each reporter personally. Despite the earlier objections to it and probably largely because there is no other one-word verb in the language to express the same idea, this use of contact has become standard in all types of speech and writing. Contact as a noun meaning “a person through whom one can gain access to information and the like” is also standard: My contact at the embassy says that the coup has been successful.
