# Stemming
{doctitle} is a process which reduces words to their stem, base, or root form by removing inflection.
The [index](https://docs.coveo.com/en/204/) uses the stem of each [queried](https://docs.coveo.com/en/231/) term to expand the query by searching for the original term as well as any indexed terms that share the same root.
