Inflection is the name for the extra letter or letters added to nouns, verbs, and adjectives in their different grammatical forms. Nouns are inflected in the plural, verbs are inflected in the various tenses, and adjectives are inflected in the comparative/superlative.
In the table below, you’ll find some of the most important inflection rules.
Grammar Explanations is . . .
. . . an evolving list of the structural rules and principles that determines where words are placed in phrases or sentences as well as how the language is spoken. Sometimes I run across an example that helps explain better or another “also known as”. Heck, there’s always a better way to explain it, so if it makes quicker and/or better sense, I would appreciate suggestions and comments from anyone on an area of grammar with which you struggle or on which you can contribute more understanding.
