Question 1
The suffix -ive appears in words like creative and
impulsive. In some words it takes the extended form -ative,
as in informative and talkative. What does this suffix
mean?
"-ive" forms adjectives meaning "tending to or relating to."
Creative = tending to create; impulsive = tending toward
impulse. The extended form "-ative" carries the same meaning:
informative = relating to informing. The suffix is not
interchangeable with "-ous" (full of) or "-able"
(capable of).
