Don’t is a contraction of the words do not which means not to perform or complete an action. A don’t is something that should not be accomplished or completed. The common phrase with the plural is spelled dos and don’ts. While dos has an alternate spelling (both dos and do’s is accepted by different people), don’ts is always don’ts and never don’t’s.
Interestingly, in the past it was the accepted contraction for does not as well, as in She don’t live here. Nowadays this is seen as incorrect and not proper, though some still use it. This continued usage may be on purpose or from lack of education or simply a cultural standard.
