大

• Physical Magnitude: Big, large, vast. In early texts, this often overlaps with height, denoting "high" or "lofty."
• Status and Maturity: Refers to those who have reached full growth/maturity (adult); also denotes superior rank, such as a chief or official (e.g., the development of 大人 from "adult" to "person of high rank").
• Qualitative Greatness: Significance in terms of influence, virtue, or importance.

• Attributive: Modifies a noun.
• Adverbial Intensifier: When preceding another adjective or verb, it functions as a degree adverb meaning "very," "greatly," "highly," or "significantly."

• Contrast with 太: While 大 denotes magnitude or greatness, 太 generally indicates excess or the extreme ("too much").

• In certain calligraphic styles or degraded manuscripts, this glyph can appear similar to 天.

• If "big" creates a semantic vacuum in a passage, consider whether the reading is actually 天 (Heaven) due to graphical similarity.
