FOREBODING Definition & Meaning - Merriam-Webster

FOREBODING Synonyms: 192 Similar and Opposite Words | Merriam-Webster Thesaurus

The etymology of "foreboding" comes from the Old English word forebodian, meaning "to announce beforehand" or "foretell".   It combines the prefix fore- (before) with the verb bode ("to announce," "to foretell"), which itself comes from the Old English bodian (to announce) and boda (messenger).  The noun form foreboding first appeared in Middle English around the late 14th century, initially meaning "omen" or "portent" before evolving to its modern sense of a feeling that something bad will happen. 

According to the Oxford English Dictionary (OED), the noun foreboding was first used in English before 1387 . The earliest evidence is found in a translation by John Trevisa.  The OED makes a distinction between the noun and adjective forms of the word:   
Noun: Earliest known use was in the Middle English period (1150–1500). The OED lists a citation from before 1387.  
Adjective: Earliest known use was in the late 1600s, with a citation from 1679. 

According to the Oxford English Dictionary (OED), the verb forebode was first used in English around 1540.  The OED cites its earliest evidence for the verb in Destruction of Troy.  It is important to distinguish the verb from the related noun forbode and the later verb bode.  
The noun forbode existed in English much earlier, in the Old English period (pre-1150).  
The modern verb bode ("to be an omen of") appeared later, in the 17th century.
