"walk through, about, or over," 1560s, from Latin perambulatus, past participle of perambulare "to walk through, go through, ramble through," from per "through" (from PIE root *per- (1) "forward," hence "through") + ambulare "to walk, go about" (see amble (v.)). Related: Perambulated; perambulating.
"much-talked-about, having celebrity, famous," 1660s, past-participle adjective from celebrate (v.).
"wander about, stray from place to place," 1590s, from Latin divagatus, past participle of divagari "to wander about," from assimilated form of dis- "apart, in different directions" (see dis-) + vagari "to wander, ramble," from vagus "strolling, wandering, rambling," figuratively "vacillating, uncertain," a word of unknown origin. Related: Divagated; divagating.
word-forming element of verbs and nouns from verbs, with a wide range of meaning: "about, around; thoroughly, completely; to make, cause, seem; to provide with; at, on, to, for;" from Old English be- "about, around, on all sides" (the unstressed form of bi "by;" see by (prep.)). The form has remained by- in stressed positions and in some more modern formations (bylaw, bygones, bystander).
The Old English prefix also was used to make transitive verbs and as a privative prefix (as in behead). The sense "on all sides, all about" naturally grew to include intensive uses (as in bespatter "spatter about," therefore "spatter very much," besprinkle, etc.). Be- also can be causative, or have just about any sense required. The prefix was productive 16c.-17c. in forming useful words, many of which have not survived, such as bethwack "to thrash soundly" (1550s) and betongue "to assail in speech, to scold" (1630s).
"about to give birth," literally or figuratively, 1590s, from Latin parturientem (nominative parturiens), present participle of parturire "be in labor," literally "desire to bring forth," desiderative of parire "to bring forth, bear, produce, create; bring about, accomplish" (from PIE root *pere- (1) "to produce, bring forth"). Related: Parturiency.
