Capable of being grieved; something that can cause grief or sorrow, or that can be complained about formally.
From 'grieve' (verb, meaning to cause sorrow or to file a formal complaint) plus '-able' (a suffix meaning 'capable of').
In labor law and workplace disputes, 'grievable' has a very specific meaning—it refers to issues that can be formally disputed through official channels, which shows how technical language borrows common words and gives them precise definitions.
