 Note that Vim does on-the-fly spell checking.  To make this work fast the
 word list is loaded in memory.  Thus this uses a lot of memory (1 Mbyte or
 more).  There might also be a noticeable delay when the word list is loaded,

 Vim searches for spell files in the "spell" subdirectory of the directories in
 'runtimepath'.  The name is: LL.EEE.spl, where:
 	LL	the language name
 	EEE	the value of 'encoding'
 
+The value for "LL" comes from 'spelllang', but excludes the region name.
+Examples:
+	'spelllang'	LL ~
+	en_us		en
+	en-rare		en-rare
+	medical_ca	medical
+
 Only the first file is loaded, the one that is first in 'runtimepath'.  If
 this succeeds then additionally files with the name LL.EEE.add.spl are loaded.
 All the ones that are found are used.
 
+Additionally, the file related to 'spellfile' is loaded.  This is the file
+that |zg| and |zw| add good and wrong words to.
+
 Exceptions:
 - Vim uses "latin1" when 'encoding' is "iso-8859-15".  The euro sign doesn't
   matter for spelling.
