The words of a will are to be taken in their ordinary and grammatical sense, unless a clear intention to use them in another sense can be collected, and that other use can be ascertained. Technical words are not necessary to give effect to any species of disposition by a will; but technical words in a will are to be taken in their technical sense, unless the context clearly indicates a contrary intention, or unless it satisfactorily appears that the will was drawn solely by the testator, and that he was unacquainted with such technical sense.
