The spelling of the word "more knockedup" can be a bit confusing, but it follows the phonetic rules of English. The first syllable "more" is pronounced as "mɔr", with the "o" sound being pronounced as in "saw". The second syllable "knockedup" is pronounced as "nɑktʌpd", with the stress on the second syllable. The "ck" and "kp" sounds are pronounced separately, and the final "ed" is pronounced as "d" rather than "t" because the preceding sound is a voiced consonant.
The phrase "more knocked up" is a colloquial expression that often describes someone who is pregnant or has recently become pregnant outside of wedlock.
Etymologically, the term "knocked up" originated in British English during the early 19th century and was initially used to mean "to be awakened" or "to knock on someone's door". However, it later started being used to refer to a woman becoming pregnant. The exact origin of the phrase is uncertain, but it is believed to have originated as a euphemism, as the term "knocked up" implies that a woman has been impregnated after a brief encounter, without any intention for a long-term commitment.
The addition of "more" to the phrase "knocked up" does not have an established etymology, as it appears to be a wordplay or a humorous alteration of the original expression.
