To get the adjective's stem, you take the -a off the feminine singular form (the second part of the dictionary entry) and then add the appropriate endings onto it. If you need a masculine form, then you decline the adjective like a 2nd declension masculine noun (e.g., maritus).
How do you find the stem of a Latin verb?
Rule 1: To find the present stem of a verb, take off -re from the present active infinitive. This will be the second principle part of the verb given in a dictionary. Taking off the -re from amāre gives you amā-. Now you have the present stem, you can use it!
How do you determine the declension of an adjective Latin?
Each declension can be unequivocally identified by the ending of the genitive singular (-ae, -i, -is, -ūs, -ei). The stem of the noun can be identified by the form of the genitive singular as well.
