  • 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."

  • Inflection: The change of a word's form to indicate a change in its grammatical function.

  • Inflectional Termination: A suffix that combines with the final letter of the stem to create the word's termination.  The Inflectional Termination -m combined with the stem puellā- to create the form puellam.

  • Monosyllabic: Having one syllable.

  • Oblique Case: Any of the cases other than the nominative and vocative.  The genitive, ablative, accusative, and locative are the oblique cases in Latin.

  • Polysyllabic: Having more than one syllable.

  • Stem: The part of the word that contains its essential meaning.  It ends in a characteristic consonant or vowel.  The final letter combines with various Inflectional Termination to create the Case Endings.  The stem of puella is puellā-, but puell-, base of puella.  Some writers use "stem" to mean "base."

  • Stem Vowel: The characteristic final vowel at the end of one of a number of stems.  The stem vowel of the stem puellā- is , but the stem vowel of the stem puero- is -o.  There is no stem vowel in the stem tempor-.

  • Termination: A term that seems to be used synonymously with "Case Ending."
