Why “foreweep” is a great word
FOREWEEP — [Verb] To weep in anticipation of an event, thereby ushering it in with lamentation. From the English prefix fore- (meaning "before" or "in front") + the verb weep (meaning "to cry or shed tears"). Unlike "outweep," which implies a greater intensity or duration of tears, or "bewail," which mourns a present or past calamity, to foreweep is the sorrow that arrives ahead of its cause—a draft drawn on a future account of pain. It is the mother's quiet sob as she fastens the buttons on her child's first school uniform, the tear that falls onto the unbroken seal of a dreaded letter, the silent cry before the diagnosis is spoken. To foreweep is to concede that the future is already broken, for the heart understands time as a series of arrivals.
