give the word

Etymology
From the concept of using a certain word used as a signal to others that they are allowed to commence on some event. While the term originally meant that a pre-decided word was to be used, the term has since evolved to mean giving allowance for an event to commence in general, not necessarily by a specific word.

Verb

 * 1) To communicate or signal to another that an action or event is allowed to commence or should be commenced, usually but not necessarily by linguistic communication.
