In German we often find some short expressions that do not really correspond to words, but are rather used to express different emotions. For example, the expression ''Oh" is commonly used to express exclamation. This could be in situations of disappointment, pleasure or simply just surprise. In German we can often distinguish between words that contain the vowel "o" and where "o" is pronounced as a short vowel, like "Knopf", and words where "o" is pronounced as a long vowel, like "groß". Perhaps it is just a matter of coincidence, but the words containing long vowels usually tend to convey some sense of exclamation, surprise or impression. For example we can take the words "groß", "hoch", "enorm", "grob", "nobel" or "Stoß". To me these words sound very similar in the sense that they are based on the sound "oh", meaning somehow exclamation, and the consonants added in the ending and beginning of each word just make the meaning more precise. Is is it really just a matter of coincidence ?
