>From Oxford Advanced Learner's Dictionary of Current English, 6th ed.:
  se-ques-trate (also se-ques-ter) verb
   (law) to take control of sb's property or ASSETS until a debt has
         been paid
   -> se-ques-tra-tion noun

The word has gained another meaning since this book came out in the
phrase "carbon sequestration", which britannica.com defines as
"the long-term storage of carbon in plants, soils, geologic formations,
and the ocean."

I am not sure about "sequestrated" and especially about "sequestrating",
but I have added them anyway as they seem theoretically possiple and I
didn't want to risk they wouldn't hyphenate correctly.

I dunno. I don't have TeX installed.

I have modified your script into the following to be in line with the way
I set up hyphenation:
  #!/bin/sh
  printf '.mso %s.tmac\n.ll 1Z\n\\&%s\n' "$1" "$2" |
        nroff -ww -Wbreak |
        sed -E '/^$/d' |
        tr -d '\n' && echo

It hyphenates correctly, too:
  se‐ques‐tra‐tion

However, I have a file where hyphentation is setup like this:
  .mso en.tmac
  .de HY
  . hy 4
  ..

(the macro HY is used after .nh to re-enable hyphenation.)

...and the word "sequestration" simply does not hyphenate.
But when I put:
  .hw se-ques-tra-tion
after the above requests at the top of the document, it does.

I have no idea what might cause this behavior. Running groff with
-ww does not reveal anything hyphenation-related.
