Excellent work as usual. A note: tact should be tack.
You're right!It'll be corrected before it goes to print.Thank you!^_^
I must have missed the point entirely, I thought tact should be tactic.
For etymology geeks like me it's just an interesting word.https://en.wikipedia.org/wiki/Tacking_(sailing)Basically it involves rapidly changing the direction of a ship relative to the direction of the wind so that it can progress against the wind. The word eventually came to be in widespread use as a non-sailing term, as Merriam-Webster notes:"tack: a course or method of action; especially one sharply divergent from that previously followed"
