Analyse the statements below about the excerpt “I think t

Analyse the statements below about the excerpt “I think that actually made it easier for us. We always write the quickest when we have a story or we're writing about something that's happened.” (l. 14-15).

I. “Easier” is a comparative form of the adjective “easy”, and it is written this way because the spelling rule for short adjectives ending in consonant + y is to drop the y and add ier.

II. “Quickest” is a comparative form of the adverb “quick”, and it is written this way because the spelling rule for short adverbs in general is to add est.

III. If “easier” were replaced by a long adjective like “beautiful,” its comparative form would be “more beautiful”.
