Forms marked · are formed by the regular rule rather than recorded in the source data. English keeps a few hundred irregulars and the rest follow the pattern, so the rule is right far more often than not — but it is a rule, and the mark says so.
Definitions, synonyms and semantic relations for utilisation come from Princeton University’s WordNet. Commonness is measured against a corpus of everyday English. Full sources and licences.
