* -ever: This suffix indicates "in whatever way," "no matter what," or "at any time". It often combines with words like "what," "who," "where," "when," "how," etc.
* Example: whatever, whoever, wherever, whenever, however
* -evermore: This suffix indicates "forever," "always," or "continuously".
* Example: forevermore, evermore
