The spelling of the word "circumstant" can be a bit tricky, but it closely follows its pronunciation. The word is pronounced as /sərˈkʌmstənt/ with the stress falling on the second syllable. The first syllable is spelled with an "s" instead of the usual "c" because it is unstressed and pronounced as /s/. The "u" is followed by "m" to indicate that the syllable is pronounced with an /ʌ/ vowel sound. The final "t" is silent, which is similar to many words of French origin.
