The phrase "god knows how" is commonly used to express uncertainty or incredulity about something. In terms of spelling, the "god knows" part is straightforward, but the "how" can be a bit more complex. The word "how" is generally pronounced with the vowel sound /aʊ/ (as in "now" or "cow"), but in this phrase it is often pronounced with the vowel sound /əʊ/ (as in "so" or "go"). This is because the stress falls on "knows" rather than "how," causing the latter to be pronounced with a reduced vowel sound.
"God knows how" is a colloquial phrase used to express uncertainty or a lack of precise knowledge about a particular situation or task. The phrase is often employed when referring to a specific action or occurrence that has happened in a mysterious or unknown manner. It can also be used to convey the idea that the speaker is unsure about the details, reasons, or origins of a particular event or situation.
The term "god knows" implies that only a divine entity possesses the knowledge or understanding of the subject in question, emphasizing the speaker's own ignorance or inability to comprehend it fully. By adding "how" to the phrase, it further emphasizes the impossibility or lack of an explanation for the matter at hand.
When used in everyday conversation, "god knows how" can describe a wide range of circumstances, such as describing an improbable feat, an inexplicable outcome, or a complicated process that seems impossible to decipher. It conveys a sense of bewilderment, acknowledging that the speaker is unable to comprehend or make sense of a situation, leaving it to a higher power or an unknown force to possess the answers.
