Question 1
The suffix -ity appears in words like ambiguity and
clarity. In some words, the suffix takes the shorter form
-ty, as in loyalty and safety. What does this
suffix mean?
"-ity" (and its shorter form "-ty") converts adjectives
into nouns meaning "state or quality of." Ambiguity = the state of
being ambiguous; loyalty = the quality of being loyal. The shorter
form "-ty" carries an identical meaning.
