The term **卵子** (*luǎnzǐ*, "ovum" or "egg cell") is a compound word formed through a common Chinese morphological process where the core morpheme **卵** (meaning "egg" or "ovum") is combined with the nominal suffix **子**. Here, **卵** provides the essential semantic content related to a reproductive egg, while the suffix **子**—often used to form concrete nouns or to nominalize—doesn't add independent meaning but completes the word, giving it a standard, discrete lexical form similar to how "-cyte" or "-ule" might function in English biological terminology.
