Inflected form

The second term we need to learn is "inflected."

We just learned that ἀκούω is the lexical form, the form of the word that is listed in the lexicon.

The "inflected" form is any other form of a word. For example, ἀκούει is an inflected form of ἀκούω.

Here is what's happening. When words change their form we say that they "inflect." When we change a verb from "hear" (as in, "I hear") to "hears" (as in, "she hears"), we say that the word inflects. "Hear" is the lexical form. "Hears" is an inflected form.

"Inflects" just means that the word changes its form.
