The word shows the regular historical change of a to o before certain consonant clusters such as ng (compare with other examples in Middle and Modern English such as bond, song, throng, and wrong). The o-form may have also been reinforced by Old French long, from Latin longus, from the same Indo-European word. Doublet of lungo and lunge.

From Old English longe, lange, the adverbial form of the adjective lang, long. The Middle English spelling longe carried the same function forward.

From Middle English longen, from Old English langian ("to long for, yearn after, grieve for, be pained, lengthen, grow longer, summon, belong"), from Proto-West Germanic langōn, from Proto-Germanic langōną ("to desire, long for"), from Proto-Indo-European lengʷʰ- ("to be easy, be quick, jump, move around, vary"). Cognate with German langen ("to reach, be sufficient"), Swedish langa ("to push, pass by hand"), Icelandic langa ("to want, desire"), and Dutch and German verlangen ("to desire, want, long for").

From Middle English long or lang, an aphetic form of ilong or ylong, itself descended from Old English ġelong or ġelang ("along, belonging, depending, consequent"). The verb was later reinterpreted as an aphetic form of belong.

Shortening of longitude.

From Middle English longen, from Old English langian (“to belong, pertain”), from Old English *lang, which is of uncertain origin yet related to Old English ġelang (“dependent, attainable, present, belonging, consequent”), Old Saxon gilang (“ready, available”).
