  1. Latin bases sometimes occur in English on their own, with or without an extra final e.
    • Latin Base: FORT-, 'strong'
    • English Derivative: fort
    • Latin Base: VERB-, 'word'
    • English Derivative: verb
    • Latin Base: GRAV-, 'heavy'
    • English Derivative: grave
    • Latin Base: FIN-, 'end'
    • English Derivative: fine
  2. Usually however, two or more bases are combined, or prefixes and suffixes are added, as in the following:
    • FIN-, 'end' + -al, 'pertaining to' + ity, 'state of'
    • Finality.
  3. When two or more Latin bases are combined, generally an i appears between them as a connective, although frequently o and other vowels are used.
    • SACR-, 'sacred' + (i) + FIC-, 'to make'
    • Sacrifice.
  4. Sometimes Greek and Latin bases are combined in the same word. These are called hybrids.
    • (Gr.) AUT(o), 'self' + (Lat.) MOB, 'to move' + -ile
    • Automobile.
  5. Often when a prefix is added to a base that starts with a consonant, the last consonant of the prefix is “assimilated” to the first consonant of the base. One hint that this is happening will be a doubling of the consonant of the base.
    ex-, “from” + FECT-, “to make” = effect
  6. A final n in a prefix will become m before a p or a b.
    in-, “not” + POSS, “to be able” + -ible = impossible
  7. Sometimes the base itself will change when a prefix is added.
    • FACT- gives “factory” and “manufacture”, but also “effect” and “defect”
    • SED- gives “sedentary”, but also “reside”
  8. ab-, a-, abs-
    • away from
    • from
  9. ad-, ac-, ag-, etc.
