- A “tack” is so much more than a pin to hold up your favorite inspirational quote by your desk. As a noun, “tack” can be a pin or flat-headed nail; it can also be a course or approach, as well as a temporary stitch to hold fabrics together. When it comes to sailing (the origin of the expression to “change tack”), there are even more definitions.
- “Tact” is a matter of social grace and sensitivity. I recommend you have some tact if you’re choosing the correct others’ grammar.
To “change tact” doesn’t really make sense unless you’re talking about a major shift in cultural and social norms in dealing with a complex situation, which I’m guessing is not what you mean.
Remember, tacks can be handy for many things. It’s good to have tact, but don’t overdo it with your word choice.
