get_tag() │ WP 2.3.0

Retrieves a post tag by tag ID or tag object.

If you pass the $tag parameter an object, which is assumed to be the tag row object retrieved from the database, it will cache the tag data.

If you pass $tag an integer of the tag ID, then that tag will be retrieved from the database, if it isn't already cached, and passed back.

If you look at get_term(), both types will be passed through several filters and finally sanitized based on the $filter parameter value.
