Alternate

adjective: happening every other time or taking turns; in American English, also serving as a substitute

verb: to switch back and forth between two things

Alternative

noun: another option or choice that can be used instead

adjective: offering a different choice, or different from the usual way

How to remember the difference

Alternate is about turns: Monday, Wednesday, Friday, every other day. Alternative is about choices: plan A or plan B.

Good to know

Some usage guides once said alternative should only be used for exactly two choices. That rule is outdated; you can speak of several alternatives. The adjective alternate ends with a quick, unstressed sound (AWL-ter-nit), while the verb ends like late.
