Take a spelling test and track your progress: ant, ent, ance, ence words.
Many adjectives end with ent or ant. These words can be made into abstract nouns by changing ent endings into ence and ant endings into ance. e.g. different goes to difference, distant goes to distance. If a word also has a related word family word that ends in -ation, then it takes -ant / - ancy /-ial. But not every -ant word has an -ation word related to it! ent, ence, ency is usually used after a soft c, soft g or qu words.
