希

• Scarcity: Physical (sparse, thin, distant) or temporal/frequency (rare, seldom, infrequent).
• Desire and Expectation: To hope for, long for, strive for, or expect. In early contexts, this often implies an active yearning.

• Adverb: Modifies a verb to indicate low frequency ("seldom," "rarely").
• Verb: Transitive; denotes longing for or expecting an object or outcome.
• Adjective: Describes a state of being thin, sparse, or distant.

In pre-Han texts, 希 and 稀 are often interchangeable regarding physical sparsity. In later periods, a divergence occurs: 稀 typically denotes physical density (e.g., diluted liquids, thin hair), while 希 is reserved for abstract rarity, temporal frequency, and psychological longing.

To disambiguate between "rarity" and "hope," evaluate the relationship between the subject and the object: if 希 modifies the frequency of an event, it denotes scarcity/rarity; if paired with a sought-after goal, it denotes desire/expectation. In both instances, the underlying conceptual thread is distance or absence.
