01

What it is

8 parts: noun, pronoun, verb, adjective, adverb, preposition, conjunction, interjection must know
Part of speech = the word's job in this sentence: before lunch (prep.) · met before (adv.) must know
Noun = person, place, thing or idea; pronoun stands in for it: the nurse → she must know
Verb = action or state of being: lifts · wrote · is · seems must know
Adjective describes a noun; adverb describes a verb, adjective or adverb: calm · calmly must know
Preposition + its object shows time, place or direction: after dinner · under the sink
Conjunctions join: FANBOYS link equal parts · because/although/when attach a clause
Interjection = a burst of feeling set apart: Ouch! · Oh, I forgot
-ing/-ed verb forms can act as adjectives or nouns: a broken cup · Swimming relaxes me
02

The rules

Paired conjunctions stay paired: either…or · neither…nor · not only…but also
should have, never "should of": I should have called first
into = movement toward; in = location: walked into the lab · worked in the lab
a before a consonant sound, an before a vowel sound: an hour · a uniform
03

Right vs wrong

✗ It was long; therefore, most finished early → ✓ …long; however, most finished early
