The word "niggard" has caused controversy due to its similarity in sound to a highly offensive racial slur. However, it is important to note that the word "niggard" has no racial connotations and means "a stingy or miserly person." The spelling of the word is often mistaken for the offensive term due to its close phonetic similarity. The IPA phonetic transcription for "more niggard" is /mɔːr ˈnɪɡərd/ which can help distinguish it from the offensive term.
The word "niggard" itself has a debated etymology. It is derived from the Old Norse word "hnǫggva", meaning "to sting" or "to cut". It then evolved into the Middle English word "niggard", which had the sense of being stingy or miserly. It is important to clarify that this word has no connection to or derivation from racial slurs or derogatory terms for people of African descent.
The phrase "more niggard" does not have a standard or widely recognized etymology because it is not a commonly used phrase in the English language. It seems to be a combination of the word "niggard" with the comparative form "more". However, "more niggard" is not a well-established phrase, and its meaning or intended use would depend on the specific context in which it is used.
