From an e-mail message by somebody in a financial-services company:

Ok, I went back to I think 2009… So I will leave my spreadsheet in tack…

(Ellipses in original.  I don’t know what they’re doing there.)

The Latin word intact means untouched, but a lot of people seem to think that tact (or, here, tack) is a condition that something remains in if it hasn’t been destroyed or blown to pieces:

‘5 Ways to Keep Culture in Tact in a Fast-Growing Startup’ With Stephanie Mardell, VP of People at Button

Headline, “Thrive Global” (web log), 25 May 2018.

Tony Dwyer says the markets fundamentals are still in tact

Headline, “Dwyerstrategy” (web log), n. d.

Even people who know that intact is one word frequently use it to mean something like, “not destroyed”, or “still in one piece”, despite some setbacks or injury; so you’re likely to encounter a description of something as “intact” when it has very much been touched.

I searched for some examples on the Web, but got tired of sifting through all the sites that use intact as a brand-name, often with odd capitalizations:  InTact, inTACT, INTACT, intACT, and so on.  I find this popularity a bit puzzling.  Does the word inspire confidence?
