There is only one word in the English language , replacing the ? sign in the alphametic

seventeen + seventeen = ?

to make it uniquely solvable.

Find this word.

(In reply to computer solutions by Charlie)

 OOOOOOOOOOOOPS...

BAD NEWS:
Your DB is definitely richer than mine.

Good news1:
From your seven solutions my personal vocabulary got 2 new words: jewelweed and insnare(=ensnare).
Good news2: Got a better D4 version (for my archive) to warrant a single answer:

<begin>

There are at least eight English words,  that by replacing the ? sign in the alphametic

seventeen + seventeen = ?

make it uniquely solvable.

Only in one of them   S+E+V=17

Find this word.
<end>

Does it meet your approval or do you offer another  parameter?

Kudos, anyway...
