Innumerable comes from Latin innumerabilis ('countless'), from in- ('not') + numerabilis ('able to be counted'), from numerare ('to count'), from numerus ('number'). The etymological trail includes Latin in- and Latin numerus. As an adjective, innumerable means too many to be counted; very numerous. The same family is visible in derived forms such as innumerably and innumerability and related forms such as number, numeral, numerous, and enumerate. Morphologically, the word is built from the elements named in its history, so the modern form preserves a visible compound, prefix, or suffix structure.
