This post touches my heart
We use the words widow, widower, and orphan, but there is no word in our vocabulary that identifies the bereaved parent.
So I’ve coined the term willower.
will·ow·er (wĭlʹō-ər) noun
1. a. A bereaved parent. b. A person whose child, or children, has died. c. A person that willows, or grieves the death of their child, or children: Each willower processes grief in his or her own way, in his or her own time.
[From the words willow, a weeping tree that has come to symbolize deep mourning, and willpower, the strength of will to carry on—despite loss.]
