A CLOSER LOOK AT NOUNS: The difference between common nouns and proper nouns—and why it matters. A CLOSER LOOK AT PRONOUNS: The word family that enables you to refer back to words you’ve already expressed—but without having to repeat those words. A CLOSER LOOK AT VERBS: Verbs are the only part of speech whose proper forms need to be in sync with the time frame of the action or state of being the verb is expressing. A CLOSER LOOK AT MODIFIERS: The difference between adjectives and adverbs is rooted in the parts of speech they modify. SORE THUMB GRAMMAR ERRORS: Keeping your writing and speech free of the grammar errors that are easily recognized and widely regarded as “bad English”.
