Verb: A verb is a word (part of speech) that in syntax conveys an action or a state of being.

• I {verb} something

Noun: A noun is a word used to name a person, animal, place, thing or abstract idea.

• The {Noun} was according the plans

Adjective: An adjective is a name for a word that modifies (describes) a noun. Nouns are words that name a place, a person, a thing, or an idea. An adjective is a word that gives more information about the noun that goes with it (accompanies). Note: An adjective can't be plural.

• The {adjective} work gave us a high profit.

Adverb: An adverb is a word used to tell more about a verb, and it almost always answers the questions how?, when?, where?, how often?, and in what way?. Words like slowly, loudly, carefully, quickly, or sadly are all adverbs. Adverbs usually, but not always, end in -ly.

• The work was done {adverb}

Have to / Have got to

In American English we can use "I have to go", whereas in British English the form "I have got to go" is more common.

In spoken English, specially in American English, these forms are also possible:

• I gotta go now
• you gotta go now
• He's/She's gotta go
• It's gotta go
• We gotta go now
• Thew gotta go now

Note that the form is different with he/she/it, and it's not normally used in written English.

More expressions which are frequently used in informal speech are:

• gotta = go to
• gonna = going to
• wanna = want to
