(Just an aside: I was actually planning on using “acknowledgements,” which I found in a list of sixteen-letter words, and my clue was going to be: “The first sentence of my post.” However, when I looked at the spelling, I said, “that’s not right!” The preferred spelling is only 15 letters: acknowledgments. So I sadly decided not to use that word.)
Anthropomorphize?
@MissTake Got it in one. Your turn!
The new word:
AAAC CIIL LORR STTY
Hint: cats and comedians do it this way.
I think the answer is probably “no,” but…does the word include “catcall”?
No, it doesn’t.
Aristocratically?
You are correct!
Next:

Some tortoises have had one, but no people have had one.
Is it sesquicentennial?
If no one minds, I will assume I have guessed the word and move on. 
The next word includes the following letters:
CEEE IMNO OPRR SSUU
My clue is the same as before:
| N | I | S | U |
| O | M | O | S |
| E | C | U | P |
| E | R | R | E |
Like last time, my clue is to present the letters in a Wordament-like square, where you can collect a word by placing your finger on the first letter of the word and then dragging to each adjacent letter until you’ve completed the word.
… nope …
Nope, as in nobody minds? Or did I do something wrong?
Nope, as in “Nope, I thought I had the answer, but I was wrong.”
This may be a trifle harder…
superceremonious
That was fast. 
Your turn!
I am curious. Did that “magic square” ever help anybody guess my word?
AACD FIII ILNO QTSU
as in, what will happen to me if I spell this wrong.
Ya, the squares help. I just came to the thread a minute ago. I saw “super” right away. Copied to excel so I could gray out the used letters, then followed a path to not get stuck in a corner.
