What does ensphere mean?
"Ensphere" is a literary verb meaning to enclose something within a sphere, or to surround it as though it were held inside one. Formed from the prefix "en-" (meaning "to put into or onto") combined with "sphere," it entered English during the early modern period, when writers were coining expressive verbs from Latin- and Greek-derived nouns. The word appears most often in poetry and elevated prose, where it evokes a sense of total, harmonious enclosure: a dome that seems to ensphere a congregation, or a heaven that enspheres the blessed. Because a sphere surrounds equally in every direction, "ensphere" suggests an enveloping that is complete, symmetrical, and often protective or sublime rather than confining. Though rare in ordinary conversation, it remains useful to writers seeking a precise, resonant alternative to plainer words like "surround" or "enclose."
To enclose within or as if within a sphere; to surround completely on all sides.
"The great dome appeared to ensphere the entire hall beneath its curve."
Chiefly poetic or formal register.
To form into a sphere or give spherical shape to.
"The sculptor sought to ensphere the block of marble into a perfect globe."
Less common than the enclosing sense.
Poets have reached for "ensphere" when plain "surround" felt too flat — Milton himself turned to it when he wanted the heavens themselves to seem like a enclosing globe.

Etymology of ensphere
"Ensphere" is formed from the prefix "en-," borrowed through Old French from Latin "in-" meaning "to put into," joined to "sphere," which derives ultimately from Greek "sphaira," meaning ball or globe. The compound took shape in early modern English, a period prolific in such formations alongside cousins like "enshrine" and "entomb." It shares its Greek root with a wide family of words including "atmosphere," "hemisphere," and "spherical." A now-obsolete variant spelling, "insphere," appears in older texts.
How ensphere is actually used
"Ensphere" is a literary and somewhat archaic word, found chiefly in poetry and elevated prose rather than everyday speech. It carries a connotation of complete, graceful enclosure — often cosmic or divine — rather than mere physical containment.
