Hindi uses the Devanagari script, which takes a few weeks to learn. Hindi has given English many everyday words, including bungalow, jungle, shampoo, and guru. Hindi grammar has two genders and verb conjugation depends on gender, which English speakers adapt to fairly quickly.

Most English speakers reach conversational Hindi in 12 to 18 months. Hindi is rated Category III by the US Foreign Service Institute at 900 hours. The Devanagari script takes a few weeks to learn. Hindi shares some vocabulary with English through Persian and Sanskrit influences, and English speakers recognize some words immediately.
Fluency in Hindi means understanding native speakers at full speed, producing natural responses without translating in your head, and maintaining conversations across varied topics. The only way to develop spoken fluency is through speaking. Reading and listening are valuable, but they do not build the speaking reflex.
