4000 Essential english words

4000 Essential English Words is a Telegram bot designed for Uzbek-speaking learners who want to study English vocabulary using the popular '4000 Essential English Words' book series. The bot greets users in Uzbek and immediately gates access behind a mandatory channel subscription check. Users must join a specific Telegram channel and tap a verify button before they can access any learning content. The bot also cross-promotes two related official bots (@Essential_english_bot and @Essential_english2_bot), suggesting a small network of complementary vocabulary bots. Monetisation appears to be limited to advertising placements, with the admin contact listed for ad inquiries.
