Except as specifically defined in § 72-84, words and phrases shall be construed according to the common and approved usage of the language, but technical words and phrases that may have acquired a peculiar and appropriate meaning in law shall be construed and understood according to such meaning.
The words "shall," "must," and "will" are mandatory in nature, establishing an obligation or duty to comply with the particular provision. The words "may" and "should" are permissive in nature.
Unless the context clearly suggests the contrary, conjunctions shall be interpreted as follows:
A. 
"And" indicates that all connected items, conditions, provisions or events apply; and
B. 
"Or" indicates that one or more of the connected items, conditions, provisions or events apply.
Words used in the present tense include the future tense. Words in the future tense include the past tense. Words used in the singular number include the plural number and the plural number includes the singular number, unless the context of the particular usage clearly indicates otherwise. Words used in the masculine gender include the feminine gender, and vice versa.
If a term used in this chapter is not defined in this article, the Zoning Administrator, or Development Administrator if the term concerns subdivisions, shall have the authority to apply a definition through the Interpretation procedure based upon the definitions used in accepted sources and dictionaries, including but not limited to A Planners Dictionary, A Glossary of Zoning, Development, and Planning Terms, the Latest Edition of the Illustrated Book of Development Definitions, and A Survey of Zoning Definitions, published by the American Planning Association.
