Chapter 5: Adjectives of the 1st and 2nd Declension in -er

• The adjectives which end in -er are similar to similar to the adjectives learned in Chapter 4 in the paradigm of "magnus, a, um": the Feminine and Neuter endings are identical to the "magnus, a, um" endings. The Masculine endings are identical to the Masculine nouns of the 2nd Declension endings in -er [e.g., puer, ager].
  
  
• Like the Masculine nouns of the 2nd Declension, some of the -er adjectives have an "e" in the stem and some do not.
  
  • This is not a big deal if you memorize the vocabulary forms as they are listed in the text: the M, F and N Nominative Singulars. The adjective will be declined with or without an "e" according to F and N forms - that is where the base is found.
  • Now you should assume: to form the adjective, just cut off the ending from the F or N Nominative Singulars. There is the base: just add the endings.
