Past Simple Affirmative Spelling Rules

When forming the past simple affirmative of regular verbs, follow these specific spelling rules:

• +ED: With most verbs, we add -ed (e.g., work - worked).
• +D: With verbs ending in -e, we add -d (e.g., live - lived).
• Y to IED: With verbs that end with a consonant + y, we change the y to -ied (e.g., try - tried, apply - applied, study - studied).
• Double Consonant: With verbs that end with a vowel + one consonant, we double the consonant (e.g., stop - stopped, plan - planned).

Prepositions of Place and Time

Prepositions provide information about the relationship of an object to another part of the sentence. To remember the role of a preposition, notice that the word position appears within the word itself.
