Examples

• miles, militis — soldier. miles means soldier; militis is the genitive form.
• milit- — the stem from the genitive militis. The genitive form helps reveal the stem used for other cases.
• militi — to or for the soldier. militi is dative singular: to or for the soldier.
• militem — the soldier as direct object. militem is accusative singular, the direct-object form.
• lux, lucis — light. lux means light; lucis gives the stem luc-.
• lucibus — to/for or by/with/from the lights. lucibus can be dative plural or ablative plural; context decides.
