The word "况且" is a conjunctive adverb formed through lexical compounding, combining the characters "况" (kuàng), which originally means "situation" or "circumstance" and here implies "given the existing situation", and "且" (qiě), which means "furthermore" or "moreover". Together, they create a logical connector meaning "moreover", "besides", or "in addition", specifically used to introduce a stronger, supplementary point that reinforces a preceding argument. Its formation is not phonetic but purely semantic, where the meaning of the whole word is derived from the contribution of both parts, evolving through classical Chinese usage into a fixed modern term for adding persuasive or explanatory information.
