# Snowball token filter [analysis-snowball-tokenfilter]


A filter that stems words using a Snowball-generated stemmer. The `language` parameter controls the stemmer with the following available values: `Arabic`, `Armenian`, `Basque`, `Catalan`, `Danish`, `Dutch`, `English`, `Estonian`, `Finnish`, `French`, `German`, `German2`, `Hungarian`, `Italian`, `Irish`, `Kp`, `Lithuanian`, `Lovins`, `Norwegian`, `Porter`, `Portuguese`, `Romanian`, `Russian`, `Serbian`, `Spanish`, `Swedish`, `Turkish`.

:::{note}
The `Kp` and `Lovins` values are deprecated in 8.16.0 and will be removed in a future version.
