Doubling the Final Consonant | Spelling Rules

The video tutorial explains how suffixes can be added to base words, sometimes requiring no changes, while in other cases, the final consonant must be doubled. The 1:1:1 rule is introduced, which states that if a one-syllable word ends with one vowel followed by one consonant, the consonant is doubled before adding suffixes like -ed or -ing. Examples such as 'run' to 'running' and 'trip' to 'tripped' are provided. The video also covers cases where doubling is not needed, such as 'dream' and 'open', due to different vowel-consonant patterns.
