The word "覃塘" is formed by combining the character "覃", which conveys meanings like depth or extension and is structurally composed of the components "西" and "早" in modern script, with "塘", meaning pond or embankment, which is formed from the semantic radical "土" (earth) and the phonetic component "唐". Together, they create a compound typically used as a place name, possibly denoting a deep or extensive pond.
