Combining Form: A form of a stem used as the first or second part of a Stem Compound. It may end with a Connecting Vowel (usually i in Latin).
Connecting Vowel: A vowel used at the end of a combining form when the next part of a Stem Compound begins with a consonant. The Connecting Vowel usually disappears when the next part of a Stem Compound begins with a vowel, unless the combining form is monosyllabic, in which case the Connecting Vowel stays. In Latin, i is the most commonly-used Connecting Vowel.
Case Ending: An ending that appears after the end of the base of a word. The case ending of puella is -a, and the case ending of puellārum is -ārum. Some grammar books refer to the Case Ending as an "Apparent Case Ending."
