Doubling a final consonant is a spelling pattern rather than a change in meaning or grammatical tense. In English spelling, an extra consonant letter often marks the preceding vowel as short. For example, doubling the n in planning distinguishes it from planing, which comes from the verb plane. Adding an extra letter keeps written forms clear and prevents confusion between different verbs.
