Regular and irregular inflections

In the Learn These Words First lessons, the regular and irregular inflections of each headword are listed:

• Nouns: singular, plural.
• Verbs: singular (1st, 2nd, 3rd person), plural, infinitive, present participle, simple past, past participle.

In the alphabetical dictionary section, only the base word and its irregular inflections are listed. Regular inflections are not shown and are formed from the base word like this:

• Adding "-s" or "-es" to make a noun plural or a verb 3rd-person singular.
• Adding "-ing" to form a verb's present participle.
• Adding "-ed" to form a verb's past tense or past participle.
• Sometimes changing the final "y" to "i" before an inflected ending.
• Sometimes dropping the final "e" or "y" before an inflected ending.
• Sometimes doubling the final consonant before an inflected ending.
