Yeldrine is a word that may be difficult to spell because of its unusual spelling. The word is pronounced /jɛlˈdrin/ (yel-DRIN), with the stress on the second syllable. The spelling includes the letter "y" instead of the more common "i" in "yellow". This is followed by the letters "e" and "l", which are pronounced as a single syllable. Finally, the word ends with the letters "d", "r", "i", "n", and "e". Yeldrine refers to a deep yellow pigment that is sometimes used in the cosmetic industry.
