-    .onWord(index = 0) { // Extension function of WordArgument
+    .addWordArgument(index = 0) { // Extension function of WordArgument
         addExecution<Player> { // extension function of PhraseCommandContext
             getArgument(0)
             this[0]
         }
     }
-    .addWordSuggestions(index = 1, suggestions = "first, "second")
+    .addWordSuggestions(index = 1, "first", "second")
+```
+```java tab="Java"
+new StellarCommand("server")
+        .addPhraseArgument("args")
+        .addWordArgument(0, argument -> {
+            argument.addExecution(context -> {
+                    context.getArgument(0);

+        })
+        .addWordSuggestions(1, "first", "second");
