Notes:
Words can also change form depending on their location in a sentence. Consider the word “this.” It is a singular pronoun, which refers to a near object. It becomes “that” when the object is far. The word also has the plural variants “these” and “those.”
The forms “is,” “am,” and “are,” are all variations of the “to be” verb, their actual expression being determined by the subject person.
Finally, the past tense “-ed” form changes depending on the type of verb used. So “live” becomes “lived” because it is a regular verb, but “feel” becomes “felt,” not “*feeled,” because it is irregular
