I am not sure that we have it covered with asegurar

Question

asegurar verbo transitivo
1 to insure
2 (garantizar) asegurar el éxito de una empresa, to ensure the success of a project
te aseguro que..., I assure you that...
3 (afianzar, sujetar) to fasten, tighten up
(wordreference.com)(dictionary.com)
If you will check insure in the dictionary, you will note the use for ensure also. It may be that asegurar applies to # 1 above.
It probably makes no difference, as recibos del seguro covers the question asked.

Answer 1

Hmmm. Interesting. I couldn't stand to see this 'unanswered' for a full year! Thanks Millie!
