The word 算是 is formed by combining the character 算, which originally means "to calculate" or "to reckon", with the character 是, which means "to be" or "yes". This fusion creates a new conceptual unit where the act of mental calculation or consideration (算) merges with the declarative force of affirmation or existence (是), yielding a sense of arriving at a concluded judgment or a conceded acknowledgment, as if one has "reckoned it to be so" after a process of thought.
