+# Stemmer token filter
+
+The `stemmer` token filter reduces words to their root or base form (also known as their _stem_).
+
+## Parameters
+
+The `stemmer` token filter can be configured with a `language` parameter that accepts the following values:
+
+- Arabic: `arabic`
+- Armenian: `armenian`
+- Basque: `basque`
+- Bengali: `bengali`
+- Brazilian Portuguese: `brazilian`
+- Bulgarian: `bulgarian`
+- Catalan: `catalan`
+- Czech: `czech`
+- Danish: `danish`
+- Dutch: `dutch, dutch_kp`
+- English: `english` (default), `light_english`, `lovins`, `minimal_english`, `porter2`, `possessive_english`
+- Estonian: `estonian`
+- Finnish: `finnish`, `light_finnish`
+- French: `light_french`, `french`, `minimal_french`
+- Galician: `galician`, `minimal_galician` (plural step only)
+- German: `light_german`, `german`, `german2`, `minimal_german`
+- Greek: `greek`
+- Hindi: `hindi`
+- Hungarian: `hungarian, light_hungarian`
+- Indonesian: `indonesian`
+- Irish: `irish`
+- Italian: `light_italian, italian`
+- Kurdish (Sorani): `sorani`
+- Latvian: `latvian`
+- Lithuanian: `lithuanian`
+- Norwegian (Bokmål): `norwegian`, `light_norwegian`, `minimal_norwegian`
+- Norwegian (Nynorsk): `light_nynorsk`, `minimal_nynorsk`
+- Portuguese: `light_portuguese`, `minimal_portuguese`, `portuguese`, `portuguese_rslp`
+- Romanian: `romanian`
+- Russian: `russian`, `light_russian`
+- Spanish: `light_spanish`, `spanish`
+- Swedish: `swedish`, `light_swedish`
+- Turkish: `turkish`
+
+You can also use the `name` parameter as an alias for the `language` parameter. If both are set, the `name` parameter is ignored.

+
+## Example
+
+The following example request creates a new index named `my-stemmer-index` and configures an analyzer with a `stemmer` filter:
+
+```json
+PUT /my-stemmer-index
+{
+  "settings": {
+    "analysis": {
+      "filter": {
+        "my_english_stemmer": {
+          "type": "stemmer",
+          "language": "english"
+        }
+      },
+      "analyzer": {
+        "my_stemmer_analyzer": {
+          "type": "custom",
+          "tokenizer": "standard",
+          "filter": [
+            "lowercase",
+            "my_english_stemmer"
+          ]
+        }
+      }
+    }
+  }
+}
+```
+{% include copy-curl.html %}
+
+## Generated tokens
+
+Use the following request to examine the tokens generated using the analyzer:
+
+```json
+GET /my-stemmer-index/_analyze
+{
+  "analyzer": "my_stemmer_analyzer",
+  "text": "running runs"
+}
+```
+{% include copy-curl.html %}
+
+The response contains the generated tokens:
+
+```json
+{
+  "tokens": [
+    {
+      "token": "run",
+      "start_offset": 0,
+      "end_offset": 7,
+      "type": "<ALPHANUM>",
+      "position": 0
+    },
+    {
+      "token": "run",
+      "start_offset": 8,
+      "end_offset": 12,
+      "type": "<ALPHANUM>",
+      "position": 1
+    }
+  ]
+}
+```
