The word "more wreakful" is not commonly used, but its spelling can be explained using the International Phonetic Alphabet (IPA). The IPA transcription of the word is /mɔːr ˈriːkfʊl/, which indicates that the first syllable is pronounced with an open o sound, and the second syllable is stressed with a long e sound. The spelling of "wreakful" indicates that it is an adjective that means "causing or involving harm or damage." Therefore, "more wreakful" would mean "even more harmful or damaging."
The word "more wreakful" does not have a clear etymology. It seems to be a combination of two words - "more" and "wreakful" - both of which have distinct origins.
1. "More": This is derived from the Old English word "māra", which means "greater or additional". It is related to the Proto-Germanic word "maizô", meaning "more".
2. "Wreakful": This term is not commonly found or used in the English language. However, "wreak" stems from the Old English "wrecan", meaning "to avenge or punish". By adding the suffix "-ful", which means "full of" or "characterized by", it creates an adjective form indicating something or someone who is "full of causing vengeance or punishment".
