Answer:
The English language recognizes eight parts of speech: noun, pronoun, verb, adjective, adverb, preposition, conjunction, and interjection.
In this sentence, parts of speech are:
- I - pronoun (first person, singular, personal pronoun);
- saw- verb (past simple tense of the verb to see)
- green - adjective (descriptive)
- watching - verb (past continuous tense of the verb to watch)
- me - pronoun (first person, singular, personal pronoun)
