We're finally using principal parts for our vocabulary list! Just to review, here's how you should read the words with multiple forms.
Nouns
(nominative singular, genitive singular) e.g. silva, silvae
If you remove the ending of the genitive singular (-ae for first declension, -ī for second declension, -is for third declension) and add the ending of any other form, you can decline the whole noun!
Verbs
(first-person singular present active indicative, present active infinitive, first-person singular perfect active indicative) e.g. dūcō, dūcere, dūxī.
More simply, you can think about it as (first-person singular present, infinitive, first-person singular perfect). It's the same thing albeit slightly less precise.
For the present and imperfect tenses, remove the ending of the second principal part (-āre, -ēre, -ere, or -īre) and add the appropriate ending! For the perfect tense, remove the ending of the third principal part (always -ī) and add the appropriate ending!
Adjectives
(masculine nominative singular, feminine nominative singular, neuter nominative singular.) e.g. mortuus, mortua, mortuum
Adjectives must agreee with the gender of their noun, so once you know what gender to use, you just decline that form of the adjective as a noun.
Other Parts of Speech
Other parts of speech by and large only have one form!
