Scire tuum nihil est, nisi te scire hoc sciat alter=--It is nothing for you to know a thing unless another knows that you know it.
And, as Nihil est, nisi hoc sciat alter, is peculiarly true of genealogy, who would not be glad to seize a fair opportunity to let it be known.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "sciat" in a variety of sentences. We hope that you will now be able to make sentences using this word.
