Apiarist is a fancy word for a beekeeper. An apiarist enjoys working with an unusual kind of pet, the honeybee. Because bees and other pollinators are so important to a healthy environment scientists encourage âbee-spottingâ to improve fruits and vegetables. The -ist suffix is a Greek form that means âa person connected with.â So, a good apiarist is probably a strong environmentalist.
