Where this word comes from
From Middle English alighten (“to descend from a place: to dismount, get off; to descend to a place: to arrive or stop (at a place); to land; to drop; to attack; of lightning: to strike; to leap on to, mount; to descend in rank; to cause (someone) to lose rank; to come forth, spring from; to alleviate, relieve; (Christianity) of Jesus: to come down to earth from heaven, become incarnate; to descend (to hell); of the Holy Spirit, angels, miracles, etc.: to descend (from heaven); to descend (upon someone); to appear in a place”) [and other forms], from a merger of: * Old English ālīhtan (“to alight, dismount”), from ā- (prefix meaning ‘away, from, off, out’) + līhtan, līehtan (“to descend, alight, light; to make easy or light, alleviate, lighten, relieve”), ultimately from Proto-Indo-European *h₁lengʷʰ- (“not heavy, light”); and * Old English ġelīhtan (“to descend; to come down, dismount; to make easy or light, alleviate, lighten, relieve”), from ġe- (intensifying prefix, attached to verbs to indicate completeness or perfection) + līhtan, līehtan (see above). The English word is analyzable as a- (prefix meaning ‘away, from, off, out’) + light (“to ease, lighten; to take off; to unload; to dismount; (archaic) to come down, land; to dismount”). Cognates * Middle Low German erlichten (“to lighten”) * Old High German gilīhten (“to make less heavy, lighten”) (Middle High German gelīhten); Old High German irlīhten (“to alleviate”) (Middle High German erlīhten, modern German erleichten)

Where this word comes from
The verb is probably derived partly: * from Middle English alighten (“to kindle, light, set on fire; to begin burning; to become bright, shine; to arouse, rouse, stir; (figuratively) to enlighten spiritually, illuminate”) [and other forms], from Old English ālīhtan, ālȳhtan (“to light up; enlighten”) (perhaps modelled after Latin illūmināre, the present active infinitive of illūminō (“to brighten, illuminate, light up”)), from ā- (prefix meaning ‘away, from, off, out’) + līhtan, līehtan (“to glow, to shine; to illuminate, to light”) (ultimately from Proto-Indo-European *lewk- (“to see; to shine; bright”)); and * from Middle English onlighten (“to cause (something) to shine; to clarify; (figuratively) to enlighten spiritually”) [and other forms], from Old English onlīhtan, a variant of inlīhtan (“to give light to, brighten, illuminate; to cause to shine; to shine; (figuratively) to give clear sight; to clear a mental fog, enlighten”), from Proto-Germanic *inliuhtijaną (“to enlighten, illumine”), from *in (“in; into”) + *liuhtijaną (“to give light, shine”) (ultimately from Proto-Indo-European *lewk-; see above); and * from later uses of alight (adjective). The English word is analysable as a- (prefix meaning ‘away, from, off, out’) + light (“to start (a fire); to burn, set fire to; to become ignited, take fire; to provide light, illuminate; to show the way by means of a light”). The adjective and adverb are derived from Late Middle English alight (adjective) [and other forms], from Old English ālīht, ālȳht, a past participle form of Old English ālīhtan, ālȳhtan (verb) (see above); but have also been subsequently interpreted as a- (prefix meaning ‘at; in; on’, used to show a condition, manner, or state) + light (“not dark or obscure, bright, clear; highly luminous”).
