Kho Chữ

Kho Chữ is a Vietnamese thesaurus and usage dictionary aimed at people who already write Vietnamese and want better word choice. It is most helpful for intermediate to advanced learners, heritage speakers, and anyone editing essays, emails, or creative writing in Vietnamese.

Instead of teaching meanings from scratch, it focuses on finding alternatives and nearby expressions. You can use it to look up a word and explore synonyms, antonyms, and related terms, then check collocations to see what combinations sound natural in real writing.

It is a handy reference when you are stuck repeating the same word or your sentence feels awkward. On the other hand, it is not designed as a full learning system, so do not expect lessons, drills, or speaking practice. Start at khochu.com and use it alongside a regular Vietnamese dictionary for definitions and nuance.
