Meet the cast — the characters who teach this
-
Cappy Capitalization — makes proper nouns and every sentence's first word stand tall; its defining act is catching a lowercase name or opener -
Pip End punctuation — gives each sentence its right ending (. ? !); catches a sentence that stops with the wrong mark or none -
Splice Comma splices & run-ons — separates two full sentences a comma wrongly glued together, or breaks a run-on that never stops -
Listy Commas in a series — sets the pauses between items in a list so the list reads cleanly -
Apostro Apostrophes — sorts possessives from contractions from plain plurals (its vs it's, dogs vs dog's) -
Echo Homophones / spelling-in-context — hears the words that sound alike and picks the right one (their / there / they're) -
Concord Subject–verb agreement — matches a verb to its subject's number (one bird sings, two birds sing) -
Tempo Verb-tense consistency — keeps a passage in one time; catches a sentence that slips from past to present -
Ana Pronoun clarity — makes every pronoun point clearly to the one noun it stands for -
Trim Concision — cuts wordiness and redundancy so the sentence says it once, clearly
