Synonym: Observance, observation.
These words are discriminated by the two distinct senses of observe. To observe means (1) to keep strictly, as, to observe a fast day, and hence, observance denotes the keeping or heeding with strictness, (2) to consider attentively, or to remark, and hence, observation denotes either the act of observing, or some remark made as the result thereof. We do not say the observation of Sunday, though the word was formerly so used. The Pharisees were curious in external observances, the astronomers are curious in celestial observations.
