Pronunciation: [ʃˈʌdəɹɪŋ] (IPA) 
The word "shuddering" is spelled with two "d"s and an "e" after the "u" because of its pronunciation. The first syllable is pronounced "shud" with a "d" sound, and the second syllable is pronounced "er" with another "d" sound. The "e" after the "u" helps elongate the vowel sound and prevent it from being pronounced as "shudder-ing" with the stress on the second syllable. The IPA transcription for "shuddering" is /ˈʃʌdərɪŋ/.
Shuddering refers to a bodily reaction characterized by sudden trembling or shaking, often involuntary, that typically occurs in response to fear, discomfort, cold temperatures, or intense emotions. It is a physiological response involving rapid and repetitive contractions of muscles, resulting in a visible and palpable shaking of the body or specific body parts.
The term "shuddering" can also describe a quivering or pulsating motion observed in inanimate objects. This usage conveys a sense of rapid and erratic movement or oscillation, similar to an uncontrollable shivering of a person experiencing fear or extreme cold.
In a psychological context, shuddering can refer to a sudden intense feeling or awareness of discomfort, dread, or repulsion, running through an individual's mind or body. This mental shuddering is often associated with a physical reaction, such as goosebumps, as a result of encountering something disturbing, unsettling, or profoundly unpleasant.
Overall, whether referring to a physical response, motion of objects, or psychological experience, shuddering denotes an involuntary and often abrupt shaking, trembling, or pulsating action, revealing a momentary disruption or heightened sensitivity to certain stimuli.
A quaking with terror or aversion.

The word "shuddering" derived from the verb "shudder", which in turn originated from Middle English "schuderen" or "shoderen" and Old English "scūderian". The Old English term can be traced back to the Proto-Germanic word "skud-", which meant "to shake" or "to tremble". This Proto-Germanic term is also related to the Old Norse word "skūða", meaning "to sway" or "to tremble". Ultimately, these words can be linked to the Proto-Indo-European root "*skeud-", with the same meaning of "to shake" or "to tremble".
