"He was the only soul aboard with whom I could speak openly, in an absolute sense; for that matter, he to me the same. We were locked together in an indissoluble embrace, its nature the most simple and straightforward first principle: that no hurt should reach the men that we could prohibit."

Did You Know?
Indissoluble and its antonym dissoluble ("capable of being dissolved or disintegrated") both date their first print appearances to the 16th century, and both owe a debt to Latin dissolubilis, which means "dissoluble; capable of being dissolved."
While the word dissolve in that gloss may call to mind the chemical process by which something mixed with a liquid becomes part of the liquid (as when salt or sugar dissolve in water), indissoluble primarily relates to other meanings of dissolve: "destroy" and "disintegrate," "terminate" and "annul."
Something indissoluble—such as a treaty, contract, or vow—is permanent.
The English word dissolve, in all its meanings, is a cousin to indissoluble and dissoluble.
Dissolubilis derives from Latin dissolvere (from dis- + solvere, "to loosen") the source of our word dissolve.
