The phrase "be available" is a common one, but there are plenty of synonyms that can be used to convey a similar meaning. Some alternatives include "be accessible," "be obtainable," "be at hand," "be on tap," and "be ready." Other options that work well in specific contexts might be "be in stock," "be open," "be free," "be vacant," or "be unoccupied." All of these synonyms imply that something is ready and waiting for use, whether it's a product, a service, or a person's time. By using these variations, writers and speakers can add some variety and nuance to their language while still getting the same message across.
