ORIGIN
early 16th century (earlier (late Middle English) as alternation): from Latin alternat- ‘done by turns’, from alternare, from alternus ‘every other’, from alter ‘other’.
USAGE
See usage at alternative.
Alternate can be a verb, noun, or adjective, while alternative can be a noun or adjective. In both American and British English, the adjective alternate means ‘every other’ ( there will be a dance on alternate Saturdays) and the adjective alternative means ‘available as another choice’ ( an alternative route; alternative medicine; alternative energy sources). In American usage, however, alternate can also be used to mean ‘available as another choice’: an alternate plan called for construction to begin immediately rather than waiting for spring. Likewise, a book club may offer an ‘alternate selection’ as an alternative to the main selection.
