Words are divided into two classes – Closed Word Classes and Open Word Classes. When we say Closed Word Classes, we mean those classes to which no more new words will be added. Thus Determiners, pronouns, prepositions and conjunctions are Closed Word Classes.Open Words classes are Nouns, verbs, adjectives and adverbs. New words are added to these categories. That is why they are called Open Word Classes.Here is a passage from the text. It contains both Closed Word Classes and Open Word Classes. Pick out the words and decide to which category they belong.On the second day, out from New York, while making the round of the promenade deck, I suddenly became aware that one of the passengers was watching me closely following me with his gaze every time I passed.I wanted to rest, to avoid the tedium of casual and importunate shipboard contacts. I gave no sign of having noticed the man.
