Someone who is obsessed with learning words can be referred to as a "logophile." Logophiles have a deep love for words and language, often enjoying the nuances, meanings, and etymology of different terms. Their passion may manifest in activities such as reading extensively, playing word games, or expanding their vocabulary through study and exploration.
