Yup, Thai basil (โหระพา, ho-ra-pa) is the kind of leaf you add to soups and Isaan salads. Holy basil (กะเพรา, ga-prao) is the kind you get in most stir fries. Lemon basil (แมงลัก, maeng-lak) the seeds are in deserts and and leaves used in some curries and soups but uncommon. Most words that were related in the sense would share the same noun before the adjective, but they look and sound like entire separate herbs.
