A misspelling of commitment; this variant appears sometimes but is considered incorrect in standard English.
A common misspelling that arose from confusion about whether the double t from commit extends through the -ment suffix. Modern spelling consensus is commitment.
Committment is one of the most common misspellings in English because the root word commit has double-t, yet people often assume it carries through—a perfect example of how spelling rules sometimes feel illogical.
