The phrase "more unfrequent" is often misspelled as "more infrequent". The correct spelling uses the prefix "un-" to reverse the meaning of the word "frequent". The pronunciation of "more unfrequent" can be written in IPA as /mɔr ʌnˈfrikwənt/. The stress is on the second syllable of "unfrequent". This phrase is commonly used to compare the relative rarity of two events or situations, indicating that one is less common than the other.
The phrase "more unfrequent" does not have a specific etymology because it is a combination of two words, "more" and "unfrequent", both of which have their own origins.
The word "more" is derived from the Old English "māra", meaning "greater" or "larger". It has remained relatively unchanged throughout the history of the English language.
"Unfrequent", on the other hand, is a combination of the prefix "un-" meaning "not" or "lack of", and the word "frequent", meaning "happening often" or "occurring regularly". "Frequent" comes from the Latin "frequens" meaning "crowded" or "numerous".
Therefore, the phrase "more unfrequent" can be understood as "less often" or "not happening regularly" depending on the context in which it is used.
