Pronunciation: [nˌɒt ʃˈə͡ʊd] (IPA) 
The correct spelling of the past tense of the verb "show" is "not shown," not "not showed." The reason for this is that the regular past tense of the verb "show" ends in "-n," not "-d," and the irregular past tense form of the verb is "shown." Therefore, adding "not" before "shown" results in "not shown." In IPA phonetic transcription, the pronunciation of "not shown" is /nɑt ʃoʊn/.
"Not showed" is a term that does not have a conventional or specific meaning in the English language. It appears to be an incorrect or incomplete phrase. However, based on the words used, one can make speculative interpretations. "Not" is a negative adverb that indicates the absence or negation of something, while "showed" is the past tense form of the verb "show," meaning to display or present something.
Combining these words, "not showed" could suggest the absence or failure of presenting or displaying something. It may refer to the act of not demonstrating, exhibiting, or revealing information, objects, emotions, or any other form of visual or observable representation. The phrase could imply that an expected or desired display or presentation did not occur or was deliberately withheld.
However, without further context or clarification, it is difficult to provide an accurate and comprehensive definition for the term "not showed." It is essential to be cautious when interpreting incomplete or potentially incorrect phrases, as their intended meaning might differ from their literal construction. To obtain a clearer understanding, additional information or clarification from the source would be necessary.
The term "not showed" does not have a specific etymology because it is not a widely recognized compound word. However, the individual words comprising "not showed" have their respective etymologies.
1. Not: The word "not" derives from Middle English and has roots in Old English "nāt", which means "not" or "neither". It is a basic negation word used to express denial or negation.
2. Showed: The word "showed" is the past tense of the verb "show", which can be traced back to Middle English "shewen" and Old English "scēawian". Its origins are possibly derived from the Proto-Germanic word "*skaugōną", meaning "to look or see". Thus, "showed" implies an action of presenting or displaying something.
