Key Usage Notes

• Old: Use elder/eldest only when referring to family members (e.g., "my elder brother"). Use older/oldest for general age and inanimate objects.
• Far: Use farther for physical distance and further for metaphorical or additional distance (e.g., "further information").
• Two-syllable adjectives: Words like quiet, clever, and narrow can often take either the "-er/-est" ending or the "more/most" prefix, though the inflected form (-er) is generally more common in modern English.
• Spelling changes:
  • Happy: The "y" changes to "i" before adding the suffix.
  • Sad: The final consonant is doubled (sadder) because it follows a short vowel.
