五

Cardinal number "five." In early philosophical, cosmological, or statecraft texts, it often functions as a taxonomic marker denoting a complete system of classification or a balanced universal set (e.g., the Five Elements 五行, Five Constants 五常). Also occurs as a surname.

Standard numeral modifier; typically precedes the noun it quantifies.

U+3405 is a graphical variant with no change in meaning.

Regarding U+4F0D (晤): While listed as a specialized semantic variant, it is not a standard substitution in literary Chinese from the Han period onward. Do not treat this as interchangeable with 五 unless the paleography of the specific manuscript strongly suggests it.
