The word "sulcations" refers to groove-like indentations on a surface. The IPA phonetic transcription for this word is /sʌlˈkeɪʃənz/. The first syllable "sul" is pronounced as "sʌl" and the "cations" part is pronounced as "ˈkeɪʃənz". The spelling of this word can be confusing due to the use of the letter "c" instead of "k" in the second syllable. However, this is because the word is derived from the Latin word "sulcus" which means "furrow" or "groove".
