What are the rules for ed in lictracy?

In literacy, the rules for using "ed" typically pertain to forming the past tense of regular verbs. Generally, you add "ed" to the base form of the verb (e.g., "walk" becomes "walked"). However, if a verb ends in "e," you simply add "d" (e.g., "love" becomes "loved"). Additionally, for verbs ending in a consonant followed by a single vowel and another consonant, you double the final consonant before adding "ed" (e.g., "stop" becomes "stopped").
