approve (esp. to sanction officially) v.t. homologate

Race cars and vehicles—even for non-motorsports events like the luge—have to be homologated to a certain set of rules so they can be deemed fit for use in competition. (Nick Yekikian, “Ever Heard The Term “Homologation Special?” This Is What It Means,” Motor Trend, 05/12/2020.)

This word can also be synonymous with allow and sanction, when used in the above sense.
