Pronunciation: [mˈɔː hˈɪsɪŋ] (IPA) 
The correct spelling of the phrase "more hissing" is /mɔːr ˈhɪsɪŋ/. The first word "more" is spelled with an "o" and not "aw" due to the presence of the vowel "o" in the IPA transcription. The second word "hissing" is spelled with a double "ss" to indicate the elongated /s/ sound. The phonetic transcription of the word helps to accurately represent the pronunciation of the word, which can often differ from its spelling.
More hissing refers to an increased amount or intensity of the sound produced by a hiss. A hiss, in this context, is a noise made by forcing one's breath through a small opening between the teeth or between the lips, usually accompanied by a sibilant or prolonged "s" sound. The term "more hissing" denotes a higher volume or greater force of the sound compared to a standard or baseline level.
The term is particularly used to describe a situation where the sound of hissing becomes more prominent or noticeable. This could occur, for example, when a person is speaking or singing and intentionally emphasizes the hissing sound for artistic or expressive purposes. More hissing can also refer to an increase in the hissing sound produced by a particular object or animal, such as a snake or a leaking pipe.
Additionally, the term can be metaphorically applied to describe a situation where there is heightened tension or conflict. Just as a hiss can indicate alarm or aggression, "more hissing" can symbolize an escalation of hostilities or disagreement between individuals or groups. It suggests an intensified level of disapproval, criticism, or animosity expressed through verbal or nonverbal means.
Overall, the dictionary definition of "more hissing" encompasses both a literal increase in the sound of hissing and a metaphorical representation of heightened confrontation or discord.
The phrase "more hissing" does not possess its own specific etymology, as it is simply a combination of two common English words.
Here is the etymology of each individual word:
1. More: The word 'more' originated from the Old English word 'māra', which stems from the West Germanic word 'mairo'. This word has roots in the Proto-Germanic language, specifically the word 'maizō'. Over time, the word evolved to 'māra' in Old English and eventually became 'more' in Modern English.
2. Hissing: The word 'hissing' came from the Old English word 'hyscan', which can be traced back to the Proto-Germanic word 'hiskaną'. This word, in turn, is derived from the Proto-Indo-European root 'kes', meaning "to hiss, jeer".
