What is the test for the interpretation of words in a statute?

It is well-established that words used in a statute "'"must be construed in context, and statutes must be harmonized, both internally and with each other, to the extent possible."'" (People v. Loeun (1997) 17 Cal.4th 1, 9.) Furthermore, effect must be given to every word, clause and sentence of a statute, if possible. A statute "'should be construed so that effect is given to all its provisions, so that no part will be inoperative or superfluous, void or insignificant, and so that one section will not destroy another unless the provision is the result of obvious mistake or error.'" (Rodriguez v. Superior Court (1993) 14 Cal.App.4th 1260, 1269.)
