DECLARE @List       NVARCHAR(MAX) = '   ab a 
x'; /*Your column/Param*/
DECLARE @Delimiter  NVARCHAR(255) = ' ';/*space*/
DECLARE @WordsTable TABLE (Data VARCHAR(1000));

/*convert by XML the string to table*/
INSERT INTO @WordsTable(Data)
SELECT Data = y.i.value('(./text())[1]', 'VARCHAR(1000)')
FROM 
( 
SELECT x = CONVERT(XML, '' 
    + REPLACE(@List, @Delimiter, '') 
    + '').query('.')
) AS a CROSS APPLY x.nodes('i') AS y(i)



/*Your total words*/
select count(*) NumberOfWords
from @WordsTable
where Data is not null;

/*words list*/
select *
from @WordsTable
where Data is not null
