The correct spelling of the phrase "was flower" can be explained through its phonetic transcription in the International Phonetic Alphabet (IPA). The /w/ sound is represented by the letter "w", the short vowel /æ/ is represented by the letter "a", and the voiced alveolar fricative /z/ is represented by the letter "z". The second word, "flower", is spelled with the letter "f" representing the voiceless labiodental fricative /f/, followed by the diphthong /laʊ/ represented by the letters "ou", and ending with the r-colored vowel /ər/ represented by the letter "er".
The phrase "was flower" does not have a standard etymology as it does not form a coherent phrase or word in English. It appears to be a combination of the past tense of the verb "to be" and the singular form of the noun "flower". However, without additional context or clarification, it is difficult to determine any specific meaning or origin for this phrase.
