English is a funny language...
Isn't it weird that a word that stems from another word can have such different meanings?
Grievances - An actual or supposed circumstance regarded as just cause for complaint. A complaint or protestation based on such a circumstance. Indignation or resentment stemming from a feeling of having been wronged.
Grieve - To cause to be sorrowful; distress; To mourn or sorrow for.
Tis a funny language eh?
Ever lost something close to your heart and it was a cause for both grief and grievance?
